Bustmaster's XM-15 platform is a proven performer. From the chrome-lined barrel, to its bolt, carrier and staked castle nut, the MOE Dissipator is built on the same heart of dependability you'll find in every Bushmaster XM-15. The six-position MOE stock with a rubber butt pad effortlessly adjusts and locks in place, while the Magpul enhanced trigger guard provides improved trigger access. Its Magpul MOE rifle-length hand guard is M-LOK compatible and has a Magpul MBUS rear flip sight.
