The MkGs Barrel & BCG Kit allows you to build a 9mm pistol-caliber carbine using CMMG®'s excellent Radial Delayed Blowback system. Unlike typical blowback systems, Radial Delayed Blowback not only reduces the weight in your BCG, it also reduces felt recoil—allowing you to stay on target and make faster follow-up shots.

The MkGs Kit is designed to work exclusively with CMMG's MkG lower receivers, but will also work with a mil-spec AR-15 upper receiver with an enlarged ejection port. Other manufacturers' receivers may work, but CMMG cannot guarantee function or reliability.
