MkG Radial Delayed Blowback™ Operating SystemSince 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.
