CMMG Banshee MK4 9mm Pistol 8" Barrel - Midnight Bronze Finish

The CMMG Banshee MK4 9mm pistol delivers AR-15 ergonomics in a compact package optimized for pistol caliber carbine performance. Built on CMMG's proven radial delayed blowback system, this 8-inch barreled platform offers superior reliability and reduced felt recoil compared to straight blowback designs.

What Makes This Different

The Banshee MK4 utilizes CMMG's patented radial delayed blowback operating system, which reduces bolt velocity by approximately 70% compared to straight blowback systems. This translates to smoother cycling, less wear on components, and significantly reduced felt recoil. The midnight bronze Cerakote finish provides enhanced corrosion resistance while maintaining a professional appearance.

Key Features

• Radial delayed blowback system reduces recoil and component wear
• 8-inch 4140 chrome moly steel barrel with 1:10 twist rate
• Midnight bronze Cerakote finish for corrosion resistance
• CMMG RipBrace pistol stabilizing brace included
• Compatible with Glock-pattern 9mm magazines
• M-LOK compatible handguard for accessory mounting
• Ambidextrous safety selector and magazine release

The 8-inch barrel length strikes an optimal balance between velocity retention and maneuverability, making this platform suitable for competitive shooting, training applications, and personal protection scenarios. The radial delayed system maintains consistent ejection patterns and reduces the violent action typical of straight blowback 9mm carbines, contributing to improved accuracy potential.
