The CMMG Banshee MKGS is a 9mm AR-platform pistol (brand part no. 99A520FCT) built around an 8-inch barrel and finished in coyote tan. CMMG engineers the Banshee line around a Fixed Ejector Radial Delayed Blowback operating system, a design tuned specifically for 9mm pistol-caliber performance rather than a repurposed rifle-caliber action. It ships with a CMMG RipBrace rather than a fixed stock, keeping the pistol short and maneuverable for close-quarters use or as a compact truck gun. This MKGS configuration suits shooters who want CMMG’s pistol-caliber platform in a distinctive coyote tan finish.
