CMMG
Overview
The CMMG Zeroed AR-15 Muzzle Brake is designed specifically for 5.56 NATO caliber rifles and features a 1/2x28 thread pitch, making it compatible with a wide range of AR-15 barrels. This muzzle brake effectively reduces recoil and muzzle rise, allowing for faster follow-up shots and improved accuracy during rapid firing. You’ll commonly find this muzzle brake in builds that utilize a carbine gas system paired with the 5.56 NATO caliber, enhancing performance for both competitive shooting and tactical applications.
