CMMG .40 S&W Barrel and BCG Kit 5" 4140 Chrome Moly, Nitride Finish

MkGs Barrel and BCG Kit allow you to build a Pistol Caliber Carbine using this Radial Delayed Blowback System which 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.



Designed to work exclusively with CMMG MkGs Lowers. Other manufacturers lowers may work, but are not guaranteed for function or reliability.
