The compensator uses ports redirected upward at various angles, creating an opposing downward force that helps reduce muzzle rise with each trigger pull. Except its ports don't all redirect gasses to the sides or back toward the shooter. The average compensator looks like a brake. The compensator greatly reduces this effect, providing a "locked in" point of aim that doesn't sway from the target as much. This effect obscures your sight picture, reduces rapid fire capability, and forces you to reset your point of aim after each shot. Unlike the recoil-reducing muzzle brake, a compensator reduces muzzle rise.Įvery time you pull the trigger, your rifle's or pistol's barrel has a tendency to rise upward. Mechanically, a compensator works just like a brake: It redirects all gas exiting the muzzle via ports cut into the device. The CompensatorĪt first glance, the compensator looks like a muzzle brake. Brakes that redirect gas to the sides can also cause discomfort to nearby shooters when at a seated range. By redirecting gas toward the shooter, a muzzle brake tends to make a firearm sound louder. Pros and ConsĪlthough a muzzle brake can reduce felt recoil and making shooting your rifle or pistol more comfortable, there are drawbacks. The brake pictured above represents the common design. But if you look closely, you'll notice the typical muzzle brake uses side vents that redirect toward the sides of the firearm or back toward the shooter. Muzzle brakes look like compensators and the two are often confused for each other. 458 SOCOM benefit the most from a good muzzle brake. Muzzle brakes reduce felt recoil, making them ideal for high-caliber rifles and pistols chambered in large calibers. This opposing force helps reduce felt recoil, improving accuracy and rapid fire capability. It does this by redirecting all gasses exiting the barrel back toward the shooter. The Muzzle BrakeĪ muzzle brake does exactly what its name implies: It literally brakes your rifle or pistol backward motion caused by recoil caused when you pull the trigger. Which one should you get, and why? We're comparing what each muzzle device does. Muzzle brakes, compensators, and flash hiders are all popular choices among AR owners. To be entirely sure of these results, I actually shot them all twice, on four separate days.Īs you can see, there is a pretty clear line between muzzle devices intended to reduce recoil and those intended to reduce flash.Your AR-15's barrel can be fitted with loads of muzzle devices. 223 and 5.56 in my house, I used 5.45 to measure sound pressure levels at the shooter’s ear. These numbers represent the average of 10 shots.Īfter I had expended every round of.

Considering that a 10 decibel difference makes something sound twice as loud, these differences should not be considered entirely minor. 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. A rifle firing supersonic ammo without a silencer? Very, very loud. Even a silenced firearm with subsonic ammo makes noise. Of course, all firearms are going to be loud. Since I forgot to take a better photo of the device, here’s a cell phone pic.Īs with the previous installment, scroll down to the charts if you’d just like to see the results.
