CMMG Radial Delayed Blowback .45 ACP BCG and 5" Barrel Combo

CMMG's patented Delayed Blowback 45 ACP system substantially reduces recoil compared to standard blowback .45 ACP builds.

Now you can build your own CMMG Delayed Blowback SBR 45 ACP rifle or pistol.

Our MkG 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.
