This machined aluminum 7.25" inch Barrel extension with a Detent locking notch takes its looks from the Browning 1919 machine gun barrel. It can be permanently attached to extend the barrel. Threaded for Sig Sauer MPX 13.5 1.5 LH threads. 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. Finished in Flat/Matte Black, weighs about 14.5 ounces. (gun & other parts sold separately)
