With an 8” barrel this is the key to building your next AR pistol or SBR that balances ballistic performance in an ergonomic and compact package.

MkG Radial Delayed Blowback™ Operating System

Since making its debut on the original .45 ACP MkG platform in 2017, Radial Delayed Blowback has revolutionized pistol caliber ARs across the entire CMMG lineup. As a result of meticulous engineering, Radial Delayed Blowback not only addressed some operational concerns with a traditional straight blowback system, but it also delivered pistol caliber carbines and personal-defense weapons with softer recoil impulses and lighter weight bolt carrier groups and buffer systems than straight blowback systems could deliver. Check out our CMMG Resources article & video to learn more about what sets Radial Delayed Blowback apart.

MkG .45 ACP uppers are only designed for use with MkG lowers, other manufacturers’ lowers may work but CMMG® cannot guarantee function.
