CMMG Banshee MKGS 40 S&W 8" 22+1 Semi-Auto Pistol

The CMMG Banshee MKGS is a compact AR-platform pistol chambered in .40 S&W, built around CMMG's innovative radial-delayed blowback operating system for soft-recoiling, reliable cycling with pistol-caliber ammunition. The MkGS platform is engineered around small-frame Glock-pattern magazines, giving this pistol a generous 22+1 capacity from a slim, controllable package.

Up front, the 8" medium-taper threaded barrel is finished in Black Nitride for durability and corrosion resistance, and is surrounded by CMMG's EML 7" M-LOK handguard for accessory mounting and a confident hold. The upper and lower receiver are machined from aluminum and finished in Black Armor Cerakote, with a flat-top Picatinny optics rail ready to accept a red dot, scope, or other aiming solution. No iron sights are included.

Controls are tuned for both right- and left-handed shooters: the CMMG Zeroed 60/90-degree ambidextrous safety is reachable from either side of the gun, and CMMG Zeroed grips provide a secure, ergonomic hold. The rear of the chassis features a black synthetic stock component that keeps the overall package compact and packable.

Each pistol ships with one 22-round Glock-pattern magazine, making this a turn-key .40 S&W package ready for the range. Proudly made in the USA, the Banshee MKGS delivers AR ergonomics and modularity in a pistol-caliber platform.
