Novox Research X-SD Muzzle Adapter and Barrel Kit - 9mm

The X-SD is a modular integrally mounted device which, when used alone, acts as a blast diffuser and linear compensator. It can also be used to mount your Bravo (HUB) or Alpha thread pattern muzzle device, should you decide to use one, so that you can enjoy every benefit of the velocity reduction that is inherent to the X-SD. The X-SD comes as a complete package. -Ported barrel -Complete X-SD shroud -Alpha (1.125x28) thread adapter -Bravo/HUB (1.375x24) thread adapter
