Dead Air Armament Muzzle Device Shim Kit 5.56 - DA001

This shim kit is designed for barrels with 1/2-28 or 5/8-24 threaded muzzles and includes three different shim thicknesses to achieve proper alignment. The kit allows users to fine-tune muzzle device spacing and concentricity. Installation requires placing the thickest shims on the barrel first.
