It provides more accuracy and gives your weapon a more tactical look. It also acts as a counterweight and aids to keep the muzzle down under rapid fire. With 9 machined ports at the end, it acts as a muzzle break as well. Fits standard 5/8x24 threaded barrels. (gun & other parts sold separately) *NEW Flat Black finish.
