Description

The CMMG Banshee MKGS is a pistol-format firearm built on CMMG’s MkGS (Glock-pattern magazine) receiver platform, chambered in 9mm Luger. The “MKGS” designation indicates native compatibility with standard Glock-pattern double-stack magazines, eliminating the need for proprietary magazines or adapter blocks. The Banshee line is built around CMMG’s Radial Delayed Blowback (RDB) operating system, which uses a rotating bolt to delay the rearward travel of the carrier at the moment of peak chamber pressure. This design reduces the perceived recoil impulse compared to straight blowback actions common in pistol-caliber carbines, and allows the use of a more compact and lightweight bolt carrier group without sacrificing reliability across a range of 9mm Luger ammunition loads.

The 8-inch barrel configuration places this firearm in the short-barreled/pistol format category, and it ships with the Ejector RIP pistol brace, which provides an additional point of contact for improved control and stability during firing. The Coyote finish is applied to the upper and lower receivers, providing a muted tan coloration suited to varied environmental conditions. This configuration is intended for roles where a compact, pistol-caliber platform with familiar Glock magazine compatibility is operationally desirable.
