The MkGs platform equipped with a host of essential AR features like last round bolt hold open, this 9mm BANSHEE MkGs is one of the most versatile pistol caliber carbines/personal defense weapons. With full length M-LOK slots on both sides and the bottom of the handguard as well as M-LOK between the top picatinny rail sections. Radial Delayed Blowback Operating System originally developed for the .45 ACP MkG platform, CMMG has adapted our Radial Delayed Blowback system across our pistol caliber lineup to create pistols and rifles with a softer recoil impulse and reduced bolt weight compared to traditional straight blowback systems.
