CMMG Banshee MK4 9mm Pistol 8" Barrel - Armor Black Finish

The CMMG Banshee MK4 9mm delivers compact firepower with AR-15 ergonomics in a pistol-caliber carbine platform. This 8-inch barreled variant combines CMMG's proven radial delayed blowback system with familiar controls for seamless operation.

What Makes This Different

The Banshee MK4 utilizes CMMG's patented Radial Delayed Blowback (RDB) operating system, eliminating the need for a traditional buffer tube while maintaining reliable cycling. Unlike straight blowback designs, the RDB system reduces felt recoil and bolt velocity, extending component life. The 8-inch barrel provides optimal velocity for 9mm ammunition while maintaining maneuverability in confined spaces.

Key Features

• Radial Delayed Blowback operating system for smooth, reliable cycling
• 8-inch 4140 chrome moly steel barrel with 1:10 twist rate
• Armor Black Cerakote finish for corrosion resistance
• AR-15 style controls and ergonomics
• M-LOK compatible handguard for accessory mounting
• Accepts Glock-pattern magazines
• Mil-spec trigger group compatibility

The MK4 excels in competitive shooting environments where rapid target engagement is crucial. Law enforcement agencies appreciate the familiar manual of arms that translates directly from AR-15 training. The 9mm chambering provides manageable recoil for extended training sessions while delivering effective terminal performance. Weather-sealed components ensure reliable function in adverse conditions.
