The kac 5.56 mams (multi-axis muzzle stability) brake has been engineered to increase controllability, to significantly reduce felt recoil and to help mitigate a rifle's flash signature as compared to traditional muzzle brake designs.The mams is a neutral bias brake that combats both muzzle rise and drift upon firing.Depending on the gun's barrel length, it can reduce felt recoil in a 5.56 x 45mm gun by as much as 67%.The 5.56 m4qd nt-4 mams is compatible with kac's qdss-nt4 5.56mm sound suppressor and comes complete with a 7-piece shim kit and installation instructions.
