Precision machined in the USA from 4140 Steel with black oxide protective coating. This muzzle brake is designed for use with 14-1 LH threaded barrels on AK-pattern rifles and pistol-style weapons. The three slots provide very effective blast and recoil reduction. The 1" x 20 OD threads allow use with our AK Projector Sleeve, which directs the muzzle blast forward and away from the shooter when used on a pistol or SBR in confined spaces such as indoors or from within a vehicle.
