CMMG
Overview
The CMMG AR-15 A2 Compensator Kit is designed for 5.56 NATO caliber firearms and features a 1/2x28 thread pitch, making it compatible with a wide range of AR-15 barrels. This compensator effectively reduces muzzle rise and helps manage recoil, providing better control during rapid fire. You’ll often find this component in mid-length gas system builds, where balancing performance and shooter comfort is crucial.
