Machined from steel with a black phosphate or blued finish, these replacements for the factory muzzle brake decrease muzzle rise and help dampen felt recoil. High quality, affordable, 922(r)-compliant parts fit the standard 14mm-1 LH thread AK muzzle for easy, fast installation. Cage is patterned after the RPK light machine gun brake to help reduce felt recoil while giving your AK a distinctive appearance.
