Effective flash suppression, reduced muzzle rise, an integrated wire cutter feature, and a slick, no frills design come together in the 6315. Machined from incredibly durable 4130 bar stock steel, the effective flash hider provides a noticeable improvement on the traditional A2 flash hider in both flash suppression and muzzle rise compensation, without increasing muzzle blast. A slick nitride finish protects it from corrosion to give you a long lasting and durable option for your rifle. Features: 1/2×28 threaded for 5.56/.223 4130 steel bar stock Properly heat treated
