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. 8 inch 4140 chrome moly steel barrel Salt bath nitride finish inside and out Radial Delayed Blowback bolt carrier group Both the barrel and BCG are designed to work with a CMMG MkG lower or a mil-spec AR-15 lower with enlarged ejection port Made in USA All NFA rules apply Backed by the CMMG Lifetime Quality Guarantee Order today!
