This machined 7 inch Barrel extension takes its looks from the Browning 1919 machine gun barrel. It is threaded for the MPA 10 & 15 series .45 acp. It provides more accuracy and gives your weapon a more tactical look. It also acts as a counter weight 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 7/8 x 9 threaded barrels for MPA .45 acp, and Vulcan .45 acp guns. It's a great upgrade that works well with our forward tactical grips. (gun & other parts sold separately)
