Description

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 we cannot guarantee function or reliability. 

**All NFA rules apply** See linked CMMG Resource article for more information.

All CMMG products come with our Lifetime Quality Guarantee.
