The Remington R51 Is Bigger Than You Think

I was excited to see the Remington R51 at SHOT, but then I saw it, and was no longer excited.

Two reasons why.

1. Remington didn’t bring any to Media Day (which, considering that they’ve had them at media events before, means only one thing: that the current iteration of pistols aren’t reliable enough)
2. It’s bigger than you’ve been led to believe.

1526457_692935160738283_769020925_n
See? It’s huge.

I made these comments on the blog’s Facebook page, and shared a photo of the R51 next to a 1911. People told me I was wrong, and that it was smaller than I was saying, because they read something on the internet. They even linked this site which purportedly offers a size comparison of the R51 and popular pistols. Here’s the R51 versus the Glock 42.

Well, here’s the R51 next to a 1911.

1521517_692067174158415_809745450_n

And here’s the Glock 42 next to my Benchmade Mini-Griptilian, which has a 6.78″ overall length.

And here’s the Remington R51 next to said Mini-Griptilian.

gr51knifewm2

These aren’t a perfect comparison, but my best guess is that the R51 is between 5/8″ and 3/4″ longer than those diagrams (and their related specifications, which claim 6″) show. If you look at the overall size of the pistol in those diagrams – and maybe this is only apparent to me because I’ve held the R51 – but it looks very wrong. Just the opening for the trigger guard, compared to the other pistols, looks way too small for human hands. Unless you shoot with your pinkie.

AR-15 Muzzle Device Comparison

This article combines the three previous parts (flash, sound, recoil) into one link.

One of the most popular accessories for today’s AR15 owner is a muzzle device. Want less muzzle flash? There’s a device for that. Want less recoil? There’s a device for that, too. Want less muzzle flash AND less recoil? Some devices even claim to perform multiple functions.

I have been closely studying how various muzzle devices perform for years, and this summer, with the assistance of Advanced Armament Company, B.E. Meyers, and Silencerco, was able to test a significant number of devices currently on the market in unique and highly educational ways. I did not manage to test all of the devices on the market, or even all of the most popular ones. I did include a good sample of different types of devices. It is my hope that after reviewing this article, the reader will be able to look at any muzzle device and be able to make an educated guess regarding its characteristics in a number of areas. As you will see, some perform quite similarly to one another.

 

Muzzle Flash

 

Introduction

 

If you would like to see how each device performed, scroll down to the graphs below. However, I feel that a preface is warranted here.

Surefire’s Micro can is not designed to reduce noise to hearing-safe levels, nor does it eliminate flash when attached to a Surefire brake.

Many manufacturers claim that their device reduces muzzle flash, and this may be true – compared to the bare muzzle. However, a bare muzzle will emit a huge amount of fiery awesomeness with most types of .223 or 5.56 ammunition. Every device tested reduced muzzle flash compared to the bare muzzle. The consumer might assume the manufacturer meant reduced muzzle flash compared to some other standard – perhaps the A2 muzzle device – which would eventually lead to disappointment.

What is your personal definition of too much muzzle flash? If your shooting only requires that you not be blinded by a huge fireball every time you pull the trigger, then nearly any device will do in this regard. However, if you want to not have bad guys see your exact position every time you shoot at them in the dark, then serious consideration must be given to which muzzle device is on the end of your rifle.

I personally feel that for combat, flash suppression is more important than sound suppression. I can hear and identify suppressed subsonic fire in my direction at over 80 yards, but if I do not have a visual reference point, I cannot effectively return fire. If someone with a very loud firearm that emits no flash is shooting at me, I am really no better informed than I would be if he had a sound suppressor. I just know that someone is shooting at me.

However, many sound suppressors, contrary to popular belief, do not do a very good job of reducing flash. So, armed with the knowledge that someone is shooting at me or my friends (from the sound) and exactly where he is shooting at me from (thanks to the flash), I would be able to shoot back with relatively high effectiveness. Of course, I would already be behind the curve, but I would have more information than the guy shooting at me would probably like. Were I the shooter instead of the shootee, this would be quite vexing.

Ammunition makes a big difference, too. Here’s the same rifle and silencer with Q3131A (the ammo used for this test) instead of S&B SS109 (the ammo used in the above photo).

With all of this in mind, this comparison uses multiple methods to evaluate muzzle flash: long-exposure photography close to the muzzle, long-exposure photography from downrange, high speed video, and high speed video using night vision equipment. Each device will be discussed individually, followed by a summary at the end of the section. Objective methods were used to analyze the results whenever possible. Winchester Q3131 was used for the still photographs and Federal M855 was used for the videos. All shots were with (unless otherwise noted) a 16″ AR15 in 5.56mm.

Images and videos are in slideshow format – look for arrows to the left and right of each slideshow photo to cycle through the images AND videos for that muzzle device.

 

Individual Device Data

 

 Bare Muzzle

This discussion must start with the baseline of “no muzzle device.”

[slideshow_deploy id=’4758′]

The bare muzzle, as stated above, allows a large (and in this case, somewhat uninspired) fireball to form in front of the muzzle. It’s by far the largest in terms of area, although with this particular evaluation method it didn’t result in the highest peak brightness. Camera settings for all shots from this angle (unless otherwise specified) were f2.8, ISO 400, 1 second shutter speed. Absolutely no modifications were made to these photos, other than to resize them.

From 80 yards downrange, it was very clear where shots were coming from – note that in this and all downrange photos, you are seeing the aggregate muzzle flash of five shots. The photos of the muzzle from the side are a single shot, but are representative of the average muzzle flash exhibited by each device in near-total darkness.

Unfortunately, we lost the high speed video file which showed the bare muzzle.

 

 

A2

The ubiquitous A2 muzzle device is sold for $5-7. It is in use on nearly all US Military M16/M4 rifles, and a significant number of civilian AR15s as well.

[slideshow_deploy id=’4760′]

Compared to the bare muzzle, the A2 offered a significant reduction in muzzle flash.

From downrange, the A2 was barely visible – I was able to spot it only because I knew exactly where the shooter was standing. If I were searching for the shooter, I would have a more difficult time – especially if he were shooting directly at me.

While photos are useful and illustrative of the overall flash allowed by each device, they show all of the light which occurred in a one second period in a single frame, which is not exactly how the human eye sees muzzle flash. The duration of muzzle flash from an AR15 with a muzzle device is approximately 1 millisecond, which is why many standard (30fps/60fps) camera videos are a poor choice for showing an entire event – a flash could be missed entirely by the camera.

High speed video, shot on Silencerco’s Phantom v12.1 at 7000fps and slowed down 10x, shows a closeup of the muzzle flash in slow motion. The duration of the visible flash is approximately 5/7000sec. It appears similar to the long exposure photography, although we can see each part as it occurs.

A still frame from high speed video, shot with a B.E. Meyers OWL night vision lens adapter, allows us to see much more flash than with the naked eye.

 

 

AAC Blackout

The Blackout is a 3 prong muzzle device described by the manufacturer as “the world’s most effective flash hider. The proprietary features eliminate muzzle flash, even on CQB-length barrels. The BLACKOUT® is inherently stronger and more impact resistant than four prong designs, while not being subject to the rapid erosion of closed-ended units.” It retails for approximately $59.

[slideshow_deploy id=’4763′]

Using the same f2.8/ISO 400/1 sec camera settings, very little visible flash was observed.

Because it was so difficult to discern the best flash hiders from one another, additional shots were taken from the side with an ISO of 1600 and no other changes. This increases the camera’s sensitivity to light, but makes the images not directly comparable to the ISO 400 shots. Only attempt to compare these shots with other ISO 1600 shots, which will be identified as such below each photo.

From downrange, I did not observe any flash. The camera captured one “spark,” but I didn’t see it until I looked at the image.

In the Phantom high speed video, only 2/7000sec of relatively small flash is seen.

Using the OWL, a small amount of flash was visible in the IR spectrum.

 

 

BattleComp 1.0

The BattleComp, according to the manufacturer, “offers muzzle control like some of the best brakes on the market, with none of their liabilities” and gives “…excellent control WITHOUT the excessive concussion and crushing blast produced by most compensators on the market — with flash comparable to an A2.” It retails for $155.

[slideshow_deploy id=’4765′]

Flash from the BattleComp was rather attractive, with tendrils of flame arcing out from the device in several directions. The muzzle flash was also immediately obvious and bright. The position of the muzzle was easily identifiable from downrange. Phantom high speed video showed significant flash which was visible for 1 millisecond, or 7/7000sec. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

B.E. Meyers 249F

The B.E. Meyers 249F is a 4 prong muzzle device which, according to the manufacturer, “virtually eliminate(s) muzzle flash.” It was originally designed for and sold to military and government customers, but recently became available on the civil market for $149.

[slideshow_deploy id=’4767′]

From the side, almost no flash was visible at ISO 400. At ISO 1600, some flash was visible, but it was still remarkably low. From downrange, no flash was visible. Keep in mind that all downrange shots show the light from 5 rounds being fired. Using the Phantom high speed camera, a very small amount of flash was visible for 3/7000sec. The B.E. Meyers OWL showed more flash on average in the IR spectrum with the 249F than the AAC Blackout.

 

 

BWA X Comp

The Black Weapons Armory X Comp is made by Proto Tactical, and is described by BWA as “produc(ing) a light straight back recoil instead of producing muzzle rise…Most compensators and flash hiders cause the muzzle to rise up and lengthen the time required for the shooter to get back on target…The X design incorporated into the tip of the compensator and interior chamber design helps reduce the flash, which produces a much smaller signature that is normally produced by muzzle brakes.”

It’s designed to control the movement of the muzzle and retails for $120.

[slideshow_deploy id=’4769′]

Flash from the X Comp was clearly visible and rather bright. From downrange, the position of the muzzle was immediately obvious. Phantom high speed video showed a relatively large muzzle flash which was visible for 6/7000sec. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

PWS FSC556

The Primary Weapons Systems FSC556 is a hybrid device which, according to PWS, “provides superior compensation characteristics combined with enough flash suppression to keep the flash out of your optics and line of sight.” It retails for $100.

[slideshow_deploy id=’4771′]

Flash from the FSC556 was greater than that of the A2 and clearly visible. From downrange, the shooter’s position could be identified with relative ease. High speed video showed a moderate amount of flash which lasted 5/7000sec. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

PWS Triad

The PWS Triad is a three prong muzzle device which retails for $70. PWS say it “features a revolutionary design bringing true flash suppression together with reduced muzzle flip by redirecting gases exiting the muzzle without the overpressure created by muzzle brakes and recoil compensators.”

[slideshow_deploy id=’4773′]

Flash was visible from the Triad, and although it was not very bright, it did cover an area of decent size. From downrange, it was slightly easier to identify the position of the Triad than the A2. High speed video showed a sizable amount of flash which was visible for 5/7000sec. The video also showed the Triad rotating as the rifle was fired due to its design (devices were not torqued for this test). No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Proto Tactical Z-Comp

Proto Tactical’s Z-Comp is a compensator with a unique angled forward end, which Proto claims “delivers significantly reduced recoil and decreases muzzle climb to help you get back on target quickly” without commenting on muzzle flash. It retails for $129.

[slideshow_deploy id=’4775′]

Flash at the muzzle was comparable to other devices of this type – that is to say, bright. Flash from downrange was very easy to spot. On high speed video, it lasted just under one millisecond. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Proto Tactical Z-Tac

Proto Tactical’s Z-Tac is a compensator with short flash suppressing tines on the front of the device. It retails for $129.

[slideshow_deploy id=’4776′]

The Z-Tac was rather flashy at the muzzle. From downrange, it was easy to spot, and flash lasted just under one millisecond on high speed video. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Rainier Arms XTC

The Rainier XTC is a hybrid device “designed to reduce felt recoil & muzzle rise with a relatively low muzzle flash. A true multi-functional muzzle device designed to do it all while looking great at an affordable price.” It retails for $57.

[slideshow_deploy id=’4777′]

The area of flash as viewed from the side was relatively small, but very bright. From 80 yards downrange, the muzzle flash was spectacular and easily seen. If you are ever stranded on a hostile planet and need to signal for help from a passing spaceship, use the XTC. High speed video shows rolling fireballs escaping out each side of the XTC, with a total flash duration of approximately 6/7000 of a second. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Silencerco Specwar Brake

The Silencerco Specwar Brake is a three port muzzle device intended to reduce recoil and provide a mounting location for the Specwar silencer. Its brother is the Saker Brake, which offers identical performance, but is intended to mount the Saker silencer. Both devices retail for $80.

[slideshow_deploy id=’4778′]

As you might expect, this device had a lot of flash. I think this was my favorite muzzle device in terms of flash. Turn your head sideways, and it looks like a Christmas tree. From downrange, the Specwar brake was easy to spot, but it was not as bright as a few of the other devices, surprisingly. Unfortunately, we didn’t get high speed video of the Specwar Brake. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Silencerco Trifecta

The Trifecta is a three prong flash hider designed to mount certain Silencerco suppressors while eliminating the ringing tone which other multi-prong devices are prone to emit when tapped on a hard surface or fired. It retails for $70.

[slideshow_deploy id=’4779′]

The Trifecta allowed a small but somewhat visible amount of flash. At 1600 ISO, the flash was easily identifiable. A small but noticeable amount of flash was visible for approximately 5/7000sec on high speed video. Although performance in the IR spectrum varied from shot to shot more than the other devices, this is a representation of the average flash visible from the Trifecta with night vision.

 

 

Simple Threaded Devices 5.56

The, uh, STD is a unique device which looks rather like an elongated thread protector and is intended to keep noise and muzzle flash from interfering with the shooter during hunting. It sells for $55.

[slideshow_deploy id=’4780′]

From the side, the STD had a noticeable amount of flash. It wasn’t terribly bright, but it was sizable. The position of the muzzle was easy enough to spot from downrange. On high speed video, the single fireball lasts just under 1 millisecond at 6/7000sec. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Spike’s Tactical Dynacomp

The Dynacomp is, according to Spike’s, “designed to reduce recoil impulse and muzzle climb to provide faster follow up shots.” No claims are made on the Spike’s Tactical site regarding muzzle flash reduction. It retails for $90.

[slideshow_deploy id=’4781′]

Muzzle flash from the Dynacomp is beautiful and awesome – and also bright. From downrange, the Dynacomp’s flash was immediately obvious. It was somewhat less than the XTC, but still unmistakable. On high speed video, the Dynacomp’s initial flash looked remarkably like the first microseconds of a nuclear explosion, lasting one millisecond, or 7/7000sec.

No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

VG6 Precision Gamma 5.56

VG6’s Gamma 556 is claimed to be “a muzzle brake and compensator hybrid. It virtually eliminates recoil and minimizes muzzle movement. The unique combination of both braking and compensating features inspire shooter confidence and allows the shooter to make very fast follow up shots.” No statements are made regarding flash suppression.

[slideshow_deploy id=’4782′]

Muzzle flash from the Gamma 556 was, as expected, healthy. The position of the shooter was easily identifiable from downrange. The VG6’s muzzle flash lasts 5/7000sec.

No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Vltor VC-1

The Vltor VC-1 is a birdcage-looking muzzle device that acts as a flash hider and mount for the Gemtech HALO silencer. It retails for $57.

[slideshow_deploy id=’4783′]

The VC-1 has muzzle flash roughly comparable to the A2. From downrange, it was a challenge to spot the VC-1 – again, about on par with the A2. On high speed video, the flash profile was also remarkably similar to that of the A2 and lasted 5/7000sec.

No night vision or ISO 1600 methods were used with this device.

 

 

YHM Phantom

The Phantom is advertised as a flash hider which “virtually eliminates flash and provides excellent performance with night vision.” It retails for $34.

[slideshow_deploy id=’4784′]

Although brighter than the Blackout and 249F, the Phantom provides rather excellent flash suppression for the price. At 1600 ISO, the flash was easily visible. From downrange, I could not identify the position of the muzzle, but flash was visible on camera (after 5 shots).

On high speed video, we can see a small amount of flash for roughly 3/7000s. Unfortunately, we lost the high speed night vision video of the Phantom.

 

 

Muzzle Flash Summary

It’s nice to look at photos and videos, but how do you quantify all of this information?

Photoshop was used for this. I resized the images and made them black and white, then used the Mosaic filter to create a blocky version of each image.

I then noted the relevant HSB data for each block, measured in relative terms, with 0 being pure black and 100 being pure white. For area, I noted the number of “blocks” for the up close images – the downrange shots all fell into one block.

Thus, we are able to compare muzzle flashes up close…

 

…as well as from downrange.

 

Due to the angles and distances involved, some of the devices performed better at distance than they did up close – and vice versa. However, the best flash hiders did well at all distances and angles.

Sound Pressure Levels

Following up on the gargantuan first post of this comparison is a relatively short yet no less important portion. Especially to civilian shooters, the sound and blast of a muzzle device can be a huge turnoff. Yeah, that new brake keeps the muzzle on target, but if the noise rattles your friends every time you shoot the rifle, and other shooters on the firing line give you dirty looks and move away? Chagrin might give you second thoughts about your purchase.

For this portion of the test, a Brüel & Kjær 2209 Impulse Precision Sound Level Meter was used. Despite having been introduced in 1971 and looking quite like it could be an important quest item in Fallout 3, this is the device specified by the US Military and used by many silencer manufacturers to measure sound pressure level. The particular meter used for the test was provided by Rob Silvers of Advanced Armament Corp.

Since I forgot to take a better photo of the device, here's a cell phone pic.
Since I forgot to take a better photo of the device, here’s a cell phone pic.

As with the previous installment, scroll down to the charts if you’d just like to see the results.

Of course, all firearms are going to be loud. Even a silenced firearm with subsonic ammo makes noise. A rifle firing supersonic ammo without a silencer? Very, very loud. We are dealing with degrees of very loud here, but the difference between the loudest and quietest device (measured to the left of the muzzle) was approximately 8 decibels. Considering that a 10 decibel difference makes something sound twice as loud, these differences should not be considered entirely minor. If you would like to read some scientific papers regarding muzzle blast and gunshot acoustics, read this, this, or this.

But now, the charts.

First, using the military standard of 1 meter left of the muzzle and 1.6 meters above the ground, using Speer Gold Dot 64gr 5.56mm. These numbers represent the average of 10 shots.

spl1meter

After I had expended every round of .223 and 5.56 in my house, I used 5.45 to measure sound pressure levels at the shooter’s ear.

splear

To be entirely sure of these results, I actually shot them all twice, on four separate days.

As you can see, there is a pretty clear line between muzzle devices intended to reduce recoil and those intended to reduce flash.

Recoil Control

Using high speed video (courtesy of Silencerco) and multiple accelerometers, I will be able to show visually as well as mathematically how effective each device in the test is at recoil reduction. During a four month period, over 1500 rounds were fired to verify g-force data from the accelerometers. The results may be surprising to some.

Rearward Forces

gforcesfinal

Not surprisingly, the most effective muzzle devices in the test were also at the loud and bright end of the spectrum in the previous tests. Silencerco’s massive Specwar triple port brake/silencer mount was by far the most effective device at recoil reduction, for example, but it was also loud and created a distinctive muzzle flash.

Downward Forces

If we think of limiting rearward forces as recoil reduction, then limiting upward forces must be called “combating muzzle rise,” right? Wrong.

Consider yourself shooting a rifle with a bare muzzle from the standing position. In scientific terms, the rifle is an arm with forces being placed upon it at the very end – the muzzle. The gases exiting the muzzle do so in a very uniform manner, with essentially no variation from side to side and top to bottom. They do not inherently cause the muzzle to move up – if the rifle were to be suspended in the air, it would move straight back.

But it’s not suspended in the air, it’s connected to your body. It has to move in some direction, because an external force has acted upon it and it is no longer “at rest.” Because your body is connected to this arm, and the rifle is long and essentially pointed at (in physics terms, not weapon terms) your body, the arm will move mostly to the rear. However, because there is much more of your body below the point where the stock meets your shoulder, and because that part of your body is eventually connected to the ground, there will be a natural tendency for the muzzle to move upwards. Unless, that is, you adjust your stance and hold to limit this effect.

In other words, the only reason “muzzle rise” exists is due to the way we position ourselves as we shoot, and we can position ourselves to minimize that, especially with a 5.56 AR-15. There is no inherent tendency for the muzzle to rise on its own. Therefore we should use devices that push the muzzle down, right?

Of course not. The ideal device in terms of muzzle control would keep the muzzle exactly where it was before the shot was fired. We don’t always fire from the standing position, and if you’re trying to shoot side prone or underneath the bumper of a car, a device which “combats muzzle rise” will be constantly forcing the muzzle left or right with every shot.

With that in mind, here’s a chart showing the downward forces caused by each device.

downwardforces

Muzzle Device Videos

For those interested in the specifics of individual devices, here are the videos, which were shot with a 16″ midlength upper on a registered full auto lower. We’ll start with the bare muzzle as a baseline and then move on to the other devices. For all videos other than the bare muzzle, the video of the rifle being fired with the specified device will be seen, semi-transparent, on top of the video of the rifle with no muzzle device being fired.

 Bare Muzzle

While a bare muzzle offers no recoil reduction, it has no quirks and recoils in a fairly straight line to the rear.

A2

The A2 did very little to retard the rearward movement of the rifle, but did force the muzzle down with every shot.

AAC Blackout

The rifle with AAC Blackout attached tracked in a nearly identical manner to the bare muzzle.

BattleComp 1.0

The BattleComp forced the muzzle down with every shot.

B.E. Meyers 249F

The 249F, for an unknown reason, tracked higher than the bare muzzle. It’s likely that this was shooter error, but all due care was given to maintaining a consistent position and stance.

BWA X-Comp

The X-Comp reduced recoil and kept the muzzle flat.

PWS FSC556

Similarly, the FSC556 reduced recoil and kept the muzzle on target.

PWS Triad

The PWS Triad forced the muzzle down more than almost any other device tested.

Proto Tactical Z-Comp

The Z-Comp did a good job of reducing recoil, but pushed the muzzle down slightly.

Proto Tactical Z-Tac

Performance of the Z-Tac was nearly identical to that of the Z-Comp.

Rainier Arms XTC

The XTC reduced recoil significantly, but pushed the muzzle down slightly with each shot.

Silencerco Specwar Brake

Recoil with the Specwar brake was minimal and straight to the rear.

Silencerco Trifecta

Performance of the Trifecta in this regard was nearly identical to the bare muzzle.

Simple Threaded Devices

The STD tracked in a nearly identical manner to the bare muzzle.

Spike’s Tactical Dynacomp

The Dynacomp pushed the muzzle down with each shot.

VG6 Precision Gamma 5.56

This early version of the VG6 Gamma reduced recoil but pushed the muzzle down significantly with each shot.

Vltor VC-1

The Vltor VC-1 reduced recoil slightly and kept the muzzle on target.

YHM Phantom

The YHM Phantom reduced recoil very slightly and kept the muzzle on target.

Overall Results

After three rounds of comparing muzzle flash, sound pressure level, and recoil reduction, how do the devices compare overall? And do I have any recommendations?

muzzledevicecompareoverall

 

For the best flash reduction, the B.E. Meyers 249F would be my choice.

For truly outstanding flash reduction at a more affordable price, the AAC Blackout is excellent.

For the best recoil reduction, the Silencerco Specwar Brake was the clear winner.

For an excellent middle ground of recoil reduction, neutral muzzle position, and fireball mitigation, the FSC556 is a great compromise.

For recoil reduction on a budget, albeit with higher muzzle flash and some downward force on the muzzle, the Rainier XTC is a good choice.

For those seeking acceptable levels of muzzle flash without cash outlays, just keep the A2 that came with your rifle.

Despite its lackluster overall showing in the test, I rather like the STD simply because of its appearance, relatively low cost, and ever-so-slight reduction in sound levels at the shooter’s ear.

Is That All She Wrote?

There may be followups to these articles as I test more devices, devise additional test methods, or write more subjective articles about each device, but this constitutes the bulk of the testing I initially set out to complete.

AR15 Muzzle Brake/Flash Hider/Compensator Comparison, Part 3

Late last year I published parts one and two of a muzzle device comparison; the third part was essentially complete at that time, but I decided to hold off on publishing it until I could verify some of my data.

Using high speed video (courtesy of Silencerco) and multiple accelerometers, I will be able to show visually as well as mathematically how effective each device in the test is at recoil reduction. During a four month period, over 1500 rounds were fired to verify g-force data from the accelerometers. The results may be surprising to some.

Rearward Forces

gforcesfinal

Not surprisingly, the most effective muzzle devices in the test were also at the loud and bright end of the spectrum in the previous tests. Silencerco’s massive Specwar triple port brake/silencer mount was by far the most effective device at recoil reduction, for example, but it was also loud and created a distinctive muzzle flash.

Downward Forces

If we think of limiting rearward forces as recoil reduction, then limiting upward forces must be called “combating muzzle rise,” right? Wrong.

We’ll start with the bare muzzle as a baseline and then move on to the other devices.

While a bare muzzle offers no recoil reduction, it has no quirks and recoils in a fairly straight line to the rear.

A2

The A2 did very little to retard the rearward movement of the rifle, but did force the muzzle down with every shot.

AAC Blackout

The rifle with AAC Blackout attached tracked in a nearly identical manner to the bare muzzle.

BattleComp 1.0

The BattleComp forced the muzzle down with every shot.

B.E. Meyers 249F

The 249F, for an unknown reason, tracked higher than the bare muzzle. It’s likely that this was shooter error, but all due care was given to maintaining a consistent position and stance.

BWA X-Comp

The X-Comp reduced recoil and kept the muzzle flat.

PWS FSC556

Similarly, the FSC556 reduced recoil and kept the muzzle on target.

PWS Triad

The PWS Triad forced the muzzle down more than almost any other device tested.

Proto Tactical Z-Comp

The Z-Comp did a good job of reducing recoil, but pushed the muzzle down slightly.

Proto Tactical Z-Tac

Performance of the Z-Tac was nearly identical to that of the Z-Comp.

Rainier Arms XTC

The XTC reduced recoil significantly, but pushed the muzzle down slightly with each shot.

Silencerco Specwar Brake

Recoil with the Specwar brake was minimal and straight to the rear.

Silencerco Trifecta

Performance of the Trifecta in this regard was nearly identical to the bare muzzle.

Simple Threaded Devices

The STD tracked in a nearly identical manner to the bare muzzle.

Spike’s Tactical Dynacomp

The Dynacomp pushed the muzzle down with each shot.

VG6 Precision Gamma 5.56

This early version of the VG6 Gamma reduced recoil but pushed the muzzle down significantly with each shot.

Vltor VC-1

The Vltor VC-1 reduced recoil slightly and kept the muzzle on target.

YHM Phantom

The YHM Phantom reduced recoil very slightly and kept the muzzle on target.

Overall Results

After three rounds of comparing muzzle flash, sound pressure level, and recoil reduction, how do the devices compare overall? And do I have any recommendations?

muzzledevicecompareoverall

 

For the best flash reduction, the B.E. Meyers 249F would be my choice.

For truly outstanding flash reduction at a more affordable price, the AAC Blackout is excellent.

For the best recoil reduction, the Silencerco Specwar Brake was the clear winner.

For an excellent middle ground of recoil reduction, neutral muzzle position, and fireball mitigation, the FSC556 is a great compromise.

For recoil reduction on a budget, albeit with higher muzzle flash and some downward force on the muzzle, the Rainier XTC is a good choice.

For those seeking acceptable levels of muzzle flash without cash outlays, just keep the A2 that came with your rifle.

Despite its lackluster overall showing in the test, I rather like the STD simply because of its appearance, relatively low cost, and ever-so-slight reduction in sound levels at the shooter’s ear.

Is That All She Wrote?

There may be followups to these articles as I test more devices, devise additional test methods, or write more subjective articles about each device, but this constitutes the bulk of the testing I initially set out to complete.

The DeSantis Holster Company Greatly Annoys Me

Two reasons why:

1. They pay some link exchange site to spam my comments section with crap like this:

desantisspam
2. They steal my photos and use them without attribution:

desantistheft

I have recommended their holsters in the past:
desantisrec

 

I will do so no longer and will actively help quality manufacturers compete with DeSantis whenever possible. Were it not for the concealed carry boom in recent years, scumbags like DeSantis would have gone out of business long ago.

An Open Letter To Anti-Gun Politicians, Activists, and Citizens

Dear above-mentioned people,

A good compromise, in my mind, involves neither party getting exactly what they want, but settling for something that both can be somewhat satisfied with. There are few examples of true compromise in politics; most often, it seems that final legislation leaves both parties with very little to be happy with and very little resembling their original goals.

When lip service is paid to compromise and a party with a small advantage in political power attempts to ram through a bad piece of legislation, effective organization on the part of the opposition can kill the entire legislative effort and leave the party in power with nothing but spent political capital.

It’s no surprise that those efforts were an ultimate failure. Anti-gun politicians and PACs can make all the noise they want about how the NRA just won’t listen to reason, and that they really are okay with the concept of individual gun ownership. What really killed your chances of passing any kind of national legislation were the following two factors:

– Gun owners saw the proposed legislation as ineffective, not to mention an attack on their rights
– Gun owners saw the proposed legislation as failing to offer any real compromise.

I submit that changes could be made to existing executive orders and federal legislation which would offer gun owners a reason to believe that (perceived) anti-gun politicians really are as pro-Second Amendment as they claim to be. These changes would have effectively no negative impact on crime in America, for reasons I will discuss below.

If any or all of these changes were suggested in conjunction with whatever gun control legislation was proposed next, I think a lot more gun owners would at the very least listen to what politicians have to say. Of course, not all of these proposals are of equal “value,” but that value could be relative to the proposed legislation.

#1 – Remove Suppressors/Silencers From The NFA Registry

In 1934, the National Firearms Act was passed, which required the registration of all silencers, short barreled rifles and shotguns, and machine guns with the ATF. Along with this requirement was a $200 tax stamp per item. Today, the registration process takes six to twelve months, depending on a variety of factors.

Short barreled rifles/shotguns and machine guns are easily demonized and it’s harder to make arguments for their utility to non-gun people. Silencers or suppressors, on the other hand, are of great utility to almost all shooters in all situations, and there is little reason to outlaw them from a criminal standpoint. Why? They help protect hearing and they only reduce the sound of a gunshot by a small amount. They don’t completely or even partially hide the sound of a gunshot.

When I say that, I mean that a loud rifle – one with a muzzle report in the 170 decibel range – would be reduced to approximately 135 decibels at best. That’s still 20 decibels louder than the front row of a rock concert, and not hearing safe without additional hearing protection. With subsonic ammunition, a handgun might be a little quieter – say 130 decibels or so. This is a far cry from the way these devices are often perceived and portrayed. They would offer little to no benefit to criminals, but many benefits to honest citizens who shoot regularly and wish to not lose their hearing over time.

Current laws raise the barrier for entry into the silencer market too high. They also make ownership impractical as not many firearms sold in the United States are ready to mount a silencer out of the box. In other countries, such as New Zealand, using a silencer is seen as being a polite neighbor.

It would make sense for all parties to advocate for the removal of silencers from the NFA registry.

#2 – 50 State Reciprocity for Carry Permits With Decent Standards

Concealed carry is, of course, a contentious topic. Many people find the concept of private citizens carrying firearms hidden on their person abhorrent; others see it as a natural right guaranteed by the Constitution and its amendments (well, the second one in particular). I realize that not everyone will be very happy with what I propose here, but hey, this article is about compromise, right?

Ostensibly, every state allows concealed carry, although some jurisdictions effectively prevent the practice by heavily scrutinizing applicants or only allowing those with political connections to acquire a permit to legally carry a firearm. On the other end of the spectrum are states such as Alaska, Arizona, Wyoming, and Vermont, which allow concealed carry of a firearm without any type of permit.

When you travel to other states, though, you quite naturally have to abide by their laws. For those who wish to carry concealed, it’s a complicated mess of which state recognizes which other states’ permits and vice versa. This often leads to a law-abiding and well-trained individual not being able to carry a firearm in a state which might allow residents of that state or certain other states to carry.

As an example, Nevada stopped recognizing Arizona carry permits because the latter reduced training requirements for carry permits. This is rather frustrating to me, and I must direct my frustration at well-meaning pro-gun groups such as the Arizona Citizens Defense League, which pushed lawmakers to allow carry without a permit (something I like and see the utility of) and reduce training requirements in order to acquire a state permit.

The latter point is something I don’t understand – if we’re going to jump through hoops and background checks and be listed in a state database in order to get a permit, we might as well get enough “training” to allow us to carry a firearm in a neighboring state with our shiny new permit. I certainly do not appreciate the results of that particular AZCDL effort.

Therefore, I submit that just as it uses the power of the purse to force states to limit the drinking age to 21, the federal government could force states to recognize concealed carry permits, especially if those permits came with stringent training standards and a criminal background check. How? Withhold federal grant money relating to law enforcement would be one possible solution.

The most passionate anti-gun folks won’t like this because “guns are bad” and the most passionate pro-gun people won’t like this because the “Second Amendment is (their) carry permit.” That said, something similar almost passed the Senate a few years ago, albeit without minimum standards.

However, the current system, in which many states only allow their own residents to carry guns, is simply illogical. Enacting a federal standard for a concealed carry permit – including training on use of force and accuracy/proficiency requirements – and requiring states to only recognize permits meeting those standards would have a positive effect on both the ability of citizens to carry firearms for self-defense (hooray, gun people) and the quality of character and training required to do so (hooray, people who think guns are bad and that 50 state reciprocity means felons can carry guns).

I saw an argument against 50 state reciprocity which basically went like this: “some states allow a right turn on a red and some don’t, and you have to obey the laws of each state when you drive there, because each state is different and has different needs.” This analogy does not fly.

If I am pulled over for a minor traffic violation due to a confusion of the law in another state, I probably wouldn’t even get a ticket. If I was caught carrying a handgun in New York City, I’d go to jail. Furthermore, there is no state which allows only residents of that state to drive cars in said state. Yet there are plenty of states which have that type of restriction on carrying a firearm.

A government-mandated (to please the anti-gun people) and privately administered (to please the pro-gun people) system for implementing this change is a possible amendment to this concept.

#3 – End Import Restrictions On Firearms Legal In The United States

Various federal laws and executive actions – the 1968 Gun Control Act and a 1989 executive order, as well as a 2013 State Department decision – have restricted the importation of certain types of firearms which are perfectly legal to manufacture or possess in the United States. Given a robust US manufacturing base, these actions seemingly have had little or no effect on the number or type of firearms available in the US. They have simply added to the complexity, cost, and burden of acquiring firearms which are functionally identical to firearms legal in the US.

They mostly affect three types of firearms: long guns (rifles and shotguns), handguns, and historic firearms (generally rifles).

In the case of the 1968 GCA “sporting purposes” requirement for imported firearms, the bottom line is that firearms have to go through a rather silly and pointless “test” of features, awarding points for each feature, in order to determine whether or not it can be imported – and this applies to all firearms, not just “assault weapons.” This silly “sporting purposes” test results in silly things like some Glock models being equipped with a “serrated target trigger” in order to pass the test.

Given that the Supreme Court recently recognized an individual right to own a firearm for self defense in the home, requiring that a firearm have “sporting purposes” would seem to be an unconstitutional regulation, as there is nothing sporting about self defense.

Next, we come to historic firearms. Traditionally, the Civilian Marksmanship Program imports – perhaps repatriates would be a better term – American firearms sold or given to other countries during their time of need. These might include bolt action or semi-auto rifles which date to the Second World War and before. They are largely desirable as nostalgia pieces and would offer no benefit over more modern firearms to criminals. Yet the Obama Administration saw fit to block the importation of M1 Rifles and M1 Carbines from Korea, for fear of their falling into the hands of criminals – although they did not cite any examples of the hundreds of thousands of other firearms distributed by the CMP seeing widespread use as “crime guns.”

Import restrictions on firearms are illogical and ineffective. They’re easily circumvented and serve no real purpose other than to offer a political victory to placate anti-gun action groups.

That’s Pretty Much It

If you (gun control proponents) want to prove that you really aren’t completely anti-gun, sincerely offer any or all of the above (and perhaps other things I haven’t thought of) as real compromises whenever you want some new piece of legislation to pass. Otherwise, you will keep meeting a massive and well-organized wall of resistance, effective enough to completely derail your efforts.

We don’t buy it when you say that you support the Second Amendment, but then take any possible action to limit the rights of gun owners. When you fail at big things like an assault weapons ban, you go for little things like halting the importation of Korean War relics, and you think that you did something to “stop gun violence.” Basically, you look at what pro-gun groups are saying and take the opposite position, regardless of the logic behind either side’s position.

We’re left with the impression that you really don’t mean what you say. That’s why we work so hard to oppose you wherever we can. If you want different results, you’ll need to change your actions, not just your words.

Respectfully,

Andrew Tuohy

Please Don’t Thank Me For My Service

When people thank me for my military service, I am put in an awkward and uncomfortable position which I do not like at all. Through conversations with other veterans, I have found that almost all of them dislike being thanked for their service as well.

I know that most people mean well, and think that they are lifting our spirits by thanking us for our service. I know that previous generations of veterans did not receive warm welcomes when they returned home. I don’t wish to sound ungrateful. I would certainly rather feel awkward than ashamed.

It’s just that the guys I have spoken to all say the same thing – we didn’t join the military so that we would be thanked for it ten years later. Even when it’s obviously sincere, it leaves us unsure of what to say.

Speaking only for myself, many times it comes across as hollow. It’s as if they don’t know what to say about us being in the military, so they pay lip service to thanking us and move on to talking about the weather.

As to exactly why it makes me feel awkward – it is a reminder of a time that I don’t really like to visit or dwell on unless I’m with very close friends (who were in the military, generally). In real life, I avoid attracting attention to the fact that I was in the military – no veteran plates or military stickers on my cars, almost no military shirts other than my French Paratrooper shirt and a 5th Marines shirt which I wear during workouts, and if people ask me about being in the military, I try to leave it at “I was in the Navy.” But as I said above, I’m not alone in this awkward feeling.

The other day, I heard a few men talking to a guy who had been severely injured during the first part of the war in Iraq. They discussed his injury (largely without his involvement) and then capped it off with a “thanks for your service.” To the men, it probably seemed respectful. To me, it seemed like the Soldier was an animal in the zoo, a creature to be examined and praised and then ignored once a socially acceptable amount of time had been dedicated to the topic. I could see from his body language and lack of a response that he was very uncomfortable. I later spoke one-on-one with him, and he confirmed that it felt “weird” to be thanked.

On the other hand, I was in a bar with one of my Marines – a man I had not seen in seven years – last night, and somehow a bar patron found out that we were in the military (the details are slightly hazy to me). He thanked us for our service and insisted upon buying us drinks, which in my case was Macallan. Perhaps it was hypocritical of me, but I can’t turn down a good single malt, so I accepted.

In most cases, though, I simply want to be left alone. In the abstract I can appreciate the thought when it is genuine, but please don’t thank me for my service.

De Facto Gun Registration Exists In The United States

What is contained in this article is entirely anecdotal and I have no substantive proof of anything written here. I am not a conspiracy theorist, I am a realist. I have unintentionally collected this information over the last six or seven years. To me, it adds up to the ATF creating a database of who is buying what firearm.

– In 2007, I had a chat with a very nice elderly couple, owners of a small gun store. They told me that during an ATF audit, the agents had scanned or otherwise made copies of 4473s (Firearms Transaction Record). I thought to myself, “Maybe they were just confused.” I mentioned it on a gun forum and was told that it couldn’t possibly be true.

– When I worked (briefly) at a gun store later that year, it was part of my job to scan 4473s into a computer. I asked where they were going, and a manager told me that they went to corporate, and then on to ATF.

– Last year, I was sitting at home when my doorbell rang. Two polite and professional ATF agents informed me that the number of firearms I had purchased from 2007 to 2010 did not match my income. I was disappointed to learn that this fact did not come with some sort of prize or award, but suddenly wondered how they knew what I had purchased. They knew of 5 AR receivers transferred to me on one 4473 (in 2010), for which no background check had been performed. I told them that those receivers, along with most of the firearms I had transferred to me during that time, were provided for free by manufacturers for T&E purposes, and told them about my blog.

When later I asked the FFL about that transaction record, they told me that the ATF had audited their records but didn’t appear to have copied any information – although that is literally the only way they could have known about those five receivers or even the transaction itself. The receivers came from two different manufacturers, and the only time they appeared together was on that 4473, which is supposed to be only retrieved by the ATF if there is a need to trace a specific transaction (and there was no need to trace that transaction). Federal law prohibits their doing so.

– A friend was recounting an ATF audit at his gun store, and mentioned that the agents were copying information from 4473s.

I am not the first person to notice this.

What does this mean?

I think that ATF Industry Operations agents are using the excuse of auditing the quality of FFL recordkeeping to create a database of firearm owners – or at the very least transferees of certain types of firearms. This is, in essence, a defenestration of the law.

AR15 Muzzle Brake/Flash Hider/Compensator Comparison, Part 2

Following up on the gargantuan first post of this comparison is a relatively short yet no less important portion. Especially to civilian shooters, the sound and blast of a muzzle device can be a huge turnoff. Yeah, that new brake keeps the muzzle on target, but if the noise rattles your friends every time you shoot the rifle, and other shooters on the firing line give you dirty looks and move away? Chagrin might give you second thoughts about your purchase.

For this portion of the test, a Brüel & Kjær 2209 Impulse Precision Sound Level Meter was used. Despite having been introduced in 1971 and looking quite like it could be an important quest item in Fallout 3, this is the device specified by the US Military and used by many silencer manufacturers to measure sound pressure level. The particular meter used for the test was provided by Rob Silvers of Advanced Armament Corp.

Since I forgot to take a better photo of the device, here's a cell phone pic.
Since I forgot to take a better photo of the device, here’s a cell phone pic.

As with the previous installment, scroll down to the charts if you’d just like to see the results.

Of course, all firearms are going to be loud. Even a silenced firearm with subsonic ammo makes noise. A rifle firing supersonic ammo without a silencer? Very, very loud. We are dealing with degrees of very loud here, but the difference between the loudest and quietest device (measured to the left of the muzzle) was approximately 8 decibels. Considering that a 10 decibel difference makes something sound twice as loud, these differences should not be considered entirely minor. If you would like to read some scientific papers regarding muzzle blast and gunshot acoustics, read this, this, or this.

But now, the charts.

First, using the military standard of 1 meter left of the muzzle and 1.6 meters above the ground, using Speer Gold Dot 64gr 5.56mm. These numbers represent the average of 10 shots.

spl1meter

After I had expended every round of .223 and 5.56 in my house, I used 5.45 to measure sound pressure levels at the shooter’s ear.

splear

To be entirely sure of these results, I actually shot them all twice, on four separate days.

As you can see, there is a pretty clear line between muzzle devices intended to reduce recoil and those intended to reduce flash.

AR15 Muzzle Brake/Flash Hider/Compensator Comparison, Part 1

Note: While I work to verify my recoil data, I have decided to release the first part of this comparison, which covers muzzle flash.

One of the most popular accessories for today’s AR15 owner is a muzzle device. Want less muzzle flash? There’s a device for that. Want less recoil? There’s a device for that, too. Want less muzzle flash AND less recoil? Some devices even claim to perform multiple functions.

I have been closely studying how various muzzle devices perform for years, and this summer, with the assistance of Advanced Armament Company, B.E. Meyers, and Silencerco, was able to test a significant number of devices currently on the market in unique and highly educational ways. I did not manage to test all of the devices on the market, or even all of the most popular ones. I did include a good sample of different types of devices. It is my hope that after reviewing this article, the reader will be able to look at any muzzle device and be able to make an educated guess regarding its characteristics in a number of areas. As you will see, some perform quite similarly to one another.

 

 

Muzzle Flash Comparisons

 

If you would like to see how each device performed, scroll down to the graphs below. However, I feel that a preface is warranted here.

Surefire’s Micro can is not designed to reduce noise to hearing-safe levels, nor does it eliminate flash when attached to a Surefire brake.

Many manufacturers claim that their device reduces muzzle flash, and this may be true – compared to the bare muzzle. However, a bare muzzle will emit a huge amount of fiery awesomeness with most types of .223 or 5.56 ammunition. Every device tested reduced muzzle flash compared to the bare muzzle. The consumer might assume the manufacturer meant reduced muzzle flash compared to some other standard – perhaps the A2 muzzle device – which would eventually lead to disappointment.

What is your personal definition of too much muzzle flash? If your shooting only requires that you not be blinded by a huge fireball every time you pull the trigger, then nearly any device will do in this regard. However, if you want to not have bad guys see your exact position every time you shoot at them in the dark, then serious consideration must be given to which muzzle device is on the end of your rifle.

I personally feel that for combat, flash suppression is more important than sound suppression. I can hear and identify suppressed subsonic fire in my direction at over 80 yards, but if I do not have a visual reference point, I cannot effectively return fire. If someone with a very loud firearm that emits no flash is shooting at me, I am really no better informed than I would be if he had a sound suppressor. I just know that someone is shooting at me.

However, many sound suppressors, contrary to popular belief, do not do a very good job of reducing flash. So, armed with the knowledge that someone is shooting at me or my friends (from the sound) and exactly where he is shooting at me from (thanks to the flash), I would be able to shoot back with relatively high effectiveness. Of course, I would already be behind the curve, but I would have more information than the guy shooting at me would probably like. Were I the shooter instead of the shootee, this would be quite vexing.

Ammunition makes a big difference, too. Here’s the same rifle and silencer with Q3131A (the ammo used for this test) instead of S&B SS109 (the ammo used in the above photo).

With all of this in mind, this comparison uses multiple methods to evaluate muzzle flash: long-exposure photography close to the muzzle, long-exposure photography from downrange, high speed video, and high speed video using night vision equipment. Each device will be discussed individually, followed by a summary at the end of the section. Objective methods were used to analyze the results whenever possible. Winchester Q3131 was used for the still photographs and Federal M855 was used for the videos. All shots were with (unless otherwise noted) a 16″ AR15 in 5.56mm.

Images and videos are in slideshow format – look for arrows to the left and right of each slideshow photo to cycle through the images AND videos for that muzzle device.

 

 

 Bare Muzzle

This discussion must start with the baseline of “no muzzle device.”

[slideshow_deploy id=’4758′]

The bare muzzle, as stated above, allows a large (and in this case, somewhat uninspired) fireball to form in front of the muzzle. It’s by far the largest in terms of area, although with this particular evaluation method it didn’t result in the highest peak brightness. Camera settings for all shots from this angle (unless otherwise specified) were f2.8, ISO 400, 1 second shutter speed. Absolutely no modifications were made to these photos, other than to resize them.

From 80 yards downrange, it was very clear where shots were coming from – note that in this and all downrange photos, you are seeing the aggregate muzzle flash of five shots. The photos of the muzzle from the side are a single shot, but are representative of the average muzzle flash exhibited by each device in near-total darkness.

Unfortunately, we lost the high speed video file which showed the bare muzzle.

 

 

A2

The ubiquitous A2 muzzle device is sold for $5-7. It is in use on nearly all US Military M16/M4 rifles, and a significant number of civilian AR15s as well.

[slideshow_deploy id=’4760′]

Compared to the bare muzzle, the A2 offered a significant reduction in muzzle flash.

From downrange, the A2 was barely visible – I was able to spot it only because I knew exactly where the shooter was standing. If I were searching for the shooter, I would have a more difficult time – especially if he were shooting directly at me.

While photos are useful and illustrative of the overall flash allowed by each device, they show all of the light which occurred in a one second period in a single frame, which is not exactly how the human eye sees muzzle flash. The duration of muzzle flash from an AR15 with a muzzle device is approximately 1 millisecond, which is why many standard (30fps/60fps) camera videos are a poor choice for showing an entire event – a flash could be missed entirely by the camera.

High speed video, shot on Silencerco’s Phantom v12.1 at 7000fps and slowed down 10x, shows a closeup of the muzzle flash in slow motion. The duration of the visible flash is approximately 5/7000sec. It appears similar to the long exposure photography, although we can see each part as it occurs.

A still frame from high speed video, shot with a B.E. Meyers OWL night vision lens adapter, allows us to see much more flash than with the naked eye.

 

 

AAC Blackout

The Blackout is a 3 prong muzzle device described by the manufacturer as “the world’s most effective flash hider. The proprietary features eliminate muzzle flash, even on CQB-length barrels. The BLACKOUT® is inherently stronger and more impact resistant than four prong designs, while not being subject to the rapid erosion of closed-ended units.” It retails for approximately $59.

[slideshow_deploy id=’4763′]

Using the same f2.8/ISO 400/1 sec camera settings, very little visible flash was observed.

Because it was so difficult to discern the best flash hiders from one another, additional shots were taken from the side with an ISO of 1600 and no other changes. This increases the camera’s sensitivity to light, but makes the images not directly comparable to the ISO 400 shots. Only attempt to compare these shots with other ISO 1600 shots, which will be identified as such below each photo.

From downrange, I did not observe any flash. The camera captured one “spark,” but I didn’t see it until I looked at the image.

In the Phantom high speed video, only 2/7000sec of relatively small flash is seen.

Using the OWL, a small amount of flash was visible in the IR spectrum.

 

 

BattleComp 1.0

The BattleComp, according to the manufacturer, “offers muzzle control like some of the best brakes on the market, with none of their liabilities” and gives “…excellent control WITHOUT the excessive concussion and crushing blast produced by most compensators on the market — with flash comparable to an A2.” It retails for $155.

[slideshow_deploy id=’4765′]

Flash from the BattleComp was rather attractive, with tendrils of flame arcing out from the device in several directions. The muzzle flash was also immediately obvious and bright. The position of the muzzle was easily identifiable from downrange. Phantom high speed video showed significant flash which was visible for 1 millisecond, or 7/7000sec. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

B.E. Meyers 249F

The B.E. Meyers 249F is a 4 prong muzzle device which, according to the manufacturer, “virtually eliminate(s) muzzle flash.” It was originally designed for and sold to military and government customers, but recently became available on the civil market for $149.

[slideshow_deploy id=’4767′]

From the side, almost no flash was visible at ISO 400. At ISO 1600, some flash was visible, but it was still remarkably low. From downrange, no flash was visible. Keep in mind that all downrange shots show the light from 5 rounds being fired. Using the Phantom high speed camera, a very small amount of flash was visible for 3/7000sec. The B.E. Meyers OWL showed more flash on average in the IR spectrum with the 249F than the AAC Blackout.

 

 

BWA X Comp

The Black Weapons Armory X Comp is made by Proto Tactical, and is described by BWA as “produc(ing) a light straight back recoil instead of producing muzzle rise…Most compensators and flash hiders cause the muzzle to rise up and lengthen the time required for the shooter to get back on target…The X design incorporated into the tip of the compensator and interior chamber design helps reduce the flash, which produces a much smaller signature that is normally produced by muzzle brakes.”

It’s designed to control the movement of the muzzle and retails for $120.

[slideshow_deploy id=’4769′]

Flash from the X Comp was clearly visible and rather bright. From downrange, the position of the muzzle was immediately obvious. Phantom high speed video showed a relatively large muzzle flash which was visible for 6/7000sec. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

PWS FSC556

The Primary Weapons Systems FSC556 is a hybrid device which, according to PWS, “provides superior compensation characteristics combined with enough flash suppression to keep the flash out of your optics and line of sight.” It retails for $100.

[slideshow_deploy id=’4771′]

Flash from the FSC556 was greater than that of the A2 and clearly visible. From downrange, the shooter’s position could be identified with relative ease. High speed video showed a moderate amount of flash which lasted 5/7000sec. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

PWS Triad

The PWS Triad is a three prong muzzle device which retails for $70. PWS say it “features a revolutionary design bringing true flash suppression together with reduced muzzle flip by redirecting gases exiting the muzzle without the overpressure created by muzzle brakes and recoil compensators.”

[slideshow_deploy id=’4773′]

Flash was visible from the Triad, and although it was not very bright, it did cover an area of decent size. From downrange, it was slightly easier to identify the position of the Triad than the A2. High speed video showed a sizable amount of flash which was visible for 5/7000sec. The video also showed the Triad rotating as the rifle was fired due to its design (devices were not torqued for this test). No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Proto Tactical Z-Comp

Proto Tactical’s Z-Comp is a compensator with a unique angled forward end, which Proto claims “delivers significantly reduced recoil and decreases muzzle climb to help you get back on target quickly” without commenting on muzzle flash. It retails for $129.

[slideshow_deploy id=’4775′]

Flash at the muzzle was comparable to other devices of this type – that is to say, bright. Flash from downrange was very easy to spot. On high speed video, it lasted just under one millisecond. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Proto Tactical Z-Tac

Proto Tactical’s Z-Tac is a compensator with short flash suppressing tines on the front of the device. It retails for $129.

[slideshow_deploy id=’4776′]

The Z-Tac was rather flashy at the muzzle. From downrange, it was easy to spot, and flash lasted just under one millisecond on high speed video. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Rainier Arms XTC

The Rainier XTC is a hybrid device “designed to reduce felt recoil & muzzle rise with a relatively low muzzle flash. A true multi-functional muzzle device designed to do it all while looking great at an affordable price.” It retails for $57.

[slideshow_deploy id=’4777′]

The area of flash as viewed from the side was relatively small, but very bright. From 80 yards downrange, the muzzle flash was spectacular and easily seen. If you are ever stranded on a hostile planet and need to signal for help from a passing spaceship, use the XTC. High speed video shows rolling fireballs escaping out each side of the XTC, with a total flash duration of approximately 6/7000 of a second. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Silencerco Specwar Brake

The Silencerco Specwar Brake is a three port muzzle device intended to reduce recoil and provide a mounting location for the Specwar silencer. Its brother is the Saker Brake, which offers identical performance, but is intended to mount the Saker silencer. Both devices retail for $80.

[slideshow_deploy id=’4778′]

As you might expect, this device had a lot of flash. I think this was my favorite muzzle device in terms of flash. Turn your head sideways, and it looks like a Christmas tree. From downrange, the Specwar brake was easy to spot, but it was not as bright as a few of the other devices, surprisingly. Unfortunately, we didn’t get high speed video of the Specwar Brake. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Silencerco Trifecta

The Trifecta is a three prong flash hider designed to mount certain Silencerco suppressors while eliminating the ringing tone which other multi-prong devices are prone to emit when tapped on a hard surface or fired. It retails for $70.

[slideshow_deploy id=’4779′]

The Trifecta allowed a small but somewhat visible amount of flash. At 1600 ISO, the flash was easily identifiable. A small but noticeable amount of flash was visible for approximately 5/7000sec on high speed video. Although performance in the IR spectrum varied from shot to shot more than the other devices, this is a representation of the average flash visible from the Trifecta with night vision.

 

 

Simple Threaded Devices 5.56

The, uh, STD is a unique device which looks rather like an elongated thread protector and is intended to keep noise and muzzle flash from interfering with the shooter during hunting. It sells for $55.

[slideshow_deploy id=’4780′]

From the side, the STD had a noticeable amount of flash. It wasn’t terribly bright, but it was sizable. The position of the muzzle was easy enough to spot from downrange. On high speed video, the single fireball lasts just under 1 millisecond at 6/7000sec. No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Spike’s Tactical Dynacomp

The Dynacomp is, according to Spike’s, “designed to reduce recoil impulse and muzzle climb to provide faster follow up shots.” No claims are made on the Spike’s Tactical site regarding muzzle flash reduction. It retails for $90.

[slideshow_deploy id=’4781′]

Muzzle flash from the Dynacomp is beautiful and awesome – and also bright. From downrange, the Dynacomp’s flash was immediately obvious. It was somewhat less than the XTC, but still unmistakable. On high speed video, the Dynacomp’s initial flash looked remarkably like the first microseconds of a nuclear explosion, lasting one millisecond, or 7/7000sec.

No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

VG6 Precision Gamma 5.56

VG6’s Gamma 556 is claimed to be “a muzzle brake and compensator hybrid. It virtually eliminates recoil and minimizes muzzle movement. The unique combination of both braking and compensating features inspire shooter confidence and allows the shooter to make very fast follow up shots.” No statements are made regarding flash suppression.

[slideshow_deploy id=’4782′]

Muzzle flash from the Gamma 556 was, as expected, healthy. The position of the shooter was easily identifiable from downrange. The VG6’s muzzle flash lasts 5/7000sec.

No night vision or ISO 1600 methods were used with this device, due to the excessive muzzle flash.

 

 

Vltor VC-1

The Vltor VC-1 is a birdcage-looking muzzle device that acts as a flash hider and mount for the Gemtech HALO silencer. It retails for $57.

[slideshow_deploy id=’4783′]

The VC-1 has muzzle flash roughly comparable to the A2. From downrange, it was a challenge to spot the VC-1 – again, about on par with the A2. On high speed video, the flash profile was also remarkably similar to that of the A2 and lasted 5/7000sec.

No night vision or ISO 1600 methods were used with this device.

 

 

YHM Phantom

The Phantom is advertised as a flash hider which “virtually eliminates flash and provides excellent performance with night vision.” It retails for $34.

[slideshow_deploy id=’4784′]

Although brighter than the Blackout and 249F, the Phantom provides rather excellent flash suppression for the price. At 1600 ISO, the flash was easily visible. From downrange, I could not identify the position of the muzzle, but flash was visible on camera (after 5 shots).

On high speed video, we can see a small amount of flash for roughly 3/7000s. Unfortunately, we lost the high speed night vision video of the Phantom.

 

 

Muzzle Flash Summary

It’s nice to look at photos and videos, but how do you quantify all of this information?

Photoshop was used for this. I resized the images and made them black and white, then used the Mosaic filter to create a blocky version of each image.

I then noted the relevant HSB data for each block, measured in relative terms, with 0 being pure black and 100 being pure white. For area, I noted the number of “blocks” for the up close images – the downrange shots all fell into one block.

Thus, we are able to compare muzzle flashes up close…

 

…as well as from downrange.

 

Due to the angles and distances involved, some of the devices performed better at distance than they did up close – and vice versa. However, the best flash hiders did well at all distances and angles.

The next portion of this article relates to sound, and it will be released soon.
