Any rifle setup is incomplete with a solid muzzle device. These small devices can have significant benefits and dramatically improve your shooting accuracy and performance. Muzzle devices work by redirecting excess gas from the muzzle in a particular way, dampening the recoil impulse and decreasing muzzle rise.

Here we are talking about the CMMG 5.56 ZEROED Muzzle Brake, an excellent option for your AR-15 or any other rifle, SBR, or AR-pistol chambered in 5.56. This muzzle brake has a subtle and aggressive design, with a pair of large posts on both sides, which are angled to push the muzzle glasses against the recoil impulse. The two smaller ports on the top of the muzzle device help you keep the muzzle centered and decrease the muzzle rise. The CMMG .308 ZEROED Muzzle Brake does not have any ports on the bottom, preventing dust signatures when shooting from a prone position.

All CMMG Zeroed Muzzle brakes are made from 4140 Steel and come in a black nitride finish. This Muzzle brake is specifically designed for 5.56 ammo and has a 1/2"-28 TPI thread pitch. It is very easy to install and comes with a crush washer to help you properly time the muzzle device.
