Also known as: Banshee Mk17 9mm
Overview
The CMMG Banshee Mk17 is a compact 9mm pistol-caliber AR-platform firearm built around CMMG's Radial Delayed Blowback operating system, which reduces bolt weight and softens the recoil impulse compared with traditional straight blowback PCCs. The Mk17 designation indicates it feeds from SIG Sauer P320 pattern magazines, with a standard 21-round capacity. It pairs a 5-inch barrel with a ZEROED RBB muzzle brake, an EML4 M-LOK handguard, ambidextrous controls, and the CMMG RipBrace.
