The Precision Armament AFAB 5.56 hybrid brake (brand part no. A04424) is a stainless muzzle device that combines the jobs of a flash hider and a compensator. The AFAB, short for Advanced Flash Arresting Brake, uses a matrix of small passageways to cool and diffuse combustion gases, which reduces recoil, muzzle rise and flash while keeping you on target in rapid fire. It is designed for .223 and 5.56mm AR-15, M16 and M4 style rifles with 1/2-28 muzzle threads, tuned for 16-inch and 14.5-inch barrels. The closed bottom cuts the dust signature when you shoot prone.
