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. Slot offers alternate styling and recoil reduction, with a solid underside that reduces dust printing when shooting prone.
