CMMG 9MM Barrel and Bolt Carrier Group (BCG) Kit - 8"

Special Price $399.99 Regular Price $474.95

The CMMG 8" 9mm Barrel and BCG Kit allow you to build a Pistol Caliber Carbine using their Patent Pending Radial Delayed Blowback System™. Unlike typical direct blowback systems, Radial Delayed Blowback 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.

Their Barrel and Bolt Kits are designed to work exclusively with mil-spec AR-15 upper receivers with a modified ejection port, like their MkG/MkGs upper, and most mil-spec AR15 lowers when used with 9 AR Conversion mags as well as their MkGs Mk17 and Mk9* lowers. Other manufacturers’ receivers may work, but we cannot guarantee function or reliability.
