Our 8″ 9mm MkGs Barrel and BCG Kit allow 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.
Our MkGs Barrel and Bolt Kits are designed to work exclusively with a mil-spec AR-15 upper receiver and our MkGs Lowers. Other manufacturers’ receivers may work, but we cannot guarantee function or reliability.
All CMMG products come with our Lifetime Quality Guarantee.
