CMMG Banshee MK3 8.6 Blackout 12.5" Barrel 20rd 11" M-LOK Zeroed Grip

The CMMG Banshee MK3 in 8.6 Blackout delivers subsonic performance in a compact platform optimized for suppressed shooting and close-quarters applications. This pistol configuration combines CMMG's proven radial delayed blowback system with the versatility of the emerging 8.6 Blackout cartridge.

What Makes This Different

The Banshee MK3 utilizes CMMG's proprietary radial delayed blowback operating system, eliminating the need for a buffer tube while maintaining reliable cycling with both subsonic and supersonic ammunition. The 8.6 Blackout cartridge provides .30 caliber performance from a compact package, delivering superior terminal ballistics compared to traditional pistol calibers. Black nitride coating on the barrel provides enhanced corrosion resistance and extends service life beyond standard phosphate treatments.

Key Features

• Radial delayed blowback system for reliable cycling without buffer tube
• 12.5-inch black nitride treated barrel for corrosion resistance
• 11-inch M-LOK compatible handguard with multiple attachment points
• 7075-T6 aluminum construction for strength-to-weight optimization
• 20-round magazine capacity for extended shooting sessions
• CMMG Zeroed grip for consistent hand placement and control
• Ambidextrous controls for left and right-handed operation

Field performance demonstrates consistent accuracy with both 220-grain subsonic and lighter supersonic loads. The compact 12.5-inch barrel length maintains ballistic effectiveness while reducing overall system length for confined spaces. Weather-sealed components ensure reliable function in adverse conditions, making this platform suitable for law enforcement, competition shooting, and hunting applications where discretion and stopping power are priorities.
