Built with a 5" nitride-finished barrel this BANSHEE chambered in 9mm is among the shortest, most compact ARs CMMG has to offer. Capitalizing on their reputation for innovation, the MkGs platform uses the always popular 9mm double stack Glock-pattern magazines. Originally developed for the .45 ACP MkG platform, CMMG has adapted the Radial Delayed Blowback system across their pistol caliber lineup to create pistols and rifles with a softer recoil impulse and reduced bolt weight compared to traditional straight blowback systems.
