Not only can this make follow-up shots difficult by obscuring the target, but it can also be distracting for other shooters. Muzzle Blast: The 5.56 x 45 mm cartridge gives off a good-sized muzzle blast when fired.Recoil Management: While the kick of the 5.56 x 45 mm is nothing to write home about, it can still be daunting for a novice shooter, and a compensator can help bring recoil levels down to something the shooter feels comfortable with.Using a muzzle brake or compensator with these larger cartridges can help bring recoil down to a manageable level. Caliber: While the AR-15 was initially developed with the 5.56 x 45 mm cartridge in mind, some shooters choose to use larger cartridges, such as.There are several different reasons to upgrade the muzzle device that comes stock with your rifle: Reduced muzzle climb means successive shots are easier and overall control of the gun is increased, making for tighter groupings during rapid fire. What Is A Compensator?Ī compensator is designed specifically to direct the gases from the muzzle upward, thereby reducing muzzle climb. This helps keep the shooter’s position concealed when on nighttime combat operations and also helps to reduce or eliminate night blindness. What Is A Flash Suppressor?Ī flash suppressor, or flash hider, uses the rifle’s vented gases to reduce or eliminate muzzle flash. While muzzle brakes are suitable for use on smaller weapons like the AR-15, they are also often found fitted on large-caliber rifles like the Barrett M82. Since the effects of recoil are reduced, the shooter is better able to acquire and reacquire targets after firing the weapon. This lessens the effects of recoil on the body and the shoulder in particular, allowing you to keep better control of your weapon. Three muzzle device types are brakes, flash suppressors and compensators, and each have their own benefits.Ī muzzle brake is designed to redirect or deflect the high-pressure and high-velocity gases of the gun either to the side or the rear. As such, there is a wide variety of aftermarket parts available, such as foregrips, stocks, trigger groups, bolt carrier assemblies and muzzle devices. The data supports this.Since its design in 1957, the AR-15 has become one of the most popular firearms platforms in the world. I recommend Surefire flash hiders with the seals for suppressed use with Surefire silencers, for this reason. (1) is going to matter much more for many people. Whether or not (2) matters is up for debate, due to Surefire re-coring your silencer if it matters, so really, probably not an issue for the majority of people. 3-prong flash hider wins (1) and brake wins (2). 3-prong flash hider vs a brake with the seals) - the differences will be (1) backpressure and (2) blast baffle erosion under high round count. With regard to comparing non-WARCOMP mounts that do have the seals (e.g. WARCOMP mounts are intended for mostly un-suppressed use with suppressed use being only seldom frequency. This is well studied by PEW Science and discussed directly with Surefire, specifically with the designer of the silencer and mounts. The at-ear waveforms measured during testing mimic text-book shocks at the shooter's head position. With the WARCOMP, the problem is exacerbated, because in addition to lack of seals, the porting in close proximity to where the seals should be located result in almost direct gas venting. The Surefire mounts without the so-called "labrynth seals" allow gas to escape from the mount interface.
