Description
CMMG 16.1″ 1:10 twist Barrel chambered in 9mm with CMMG Radial Delayed Blowback Bolt Carrier Group. Unlike typical direct blowback systems, the 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. The CMMG Barrel and Bolt Kits are designed to work exclusively with mil-spec AR-15 upper receivers with a modified ejection port, like The CMMG MkG/MkGs upper, and most mil-spec AR15 lowers when used with 9 AR Conversion mags as well as CMMG MkGs Mk17 and Mk9* lowers. Other manufacturers’ receivers may work, but we cannot guarantee function or reliability.*Older Mk9 lowers will require one of our retrofit kits to convert it to a Radial Delayed Blowback compatible lower, instead of Traditional Blowback.
