CMMG .45ACP 5in Barrel and BCG Kit

The MkG 5 Barrel and BCG Kit in 45ACP allows you to build a Pistol Caliber Carbine using our Patent Pending Radial Delayed Blowback System. Unlike typical direct blowback systems, our RDB uses a bolt that is forced to rotate and unlock, slowing the BCG. This results in a lighter BCG for a lighter rifle, and less felt recoil than a straight blowback system. MkG Barrel and Bolt Kits are designed to work exclusively with our MkG Lowers. Other manufacturers receivers may work, but they cannot guarantee function or reliability.
