CMMG Banshee MKGS 40 S&W 8" Barrel 22+1 Capacity M-LOK Handguard

The CMMG Banshee MKGS delivers pistol-caliber carbine performance in a compact platform optimized for 40 S&W ammunition. This radial delayed blowback system eliminates the need for a buffer tube while maintaining reliable cycling across various ammunition weights. The 8-inch nitride-treated barrel provides enhanced corrosion resistance and extended service life compared to standard phosphate coatings.

What Makes This Different

The MKGS (Modified Kiss Goodbye System) utilizes CMMG's proprietary radial delayed blowback operation, reducing felt recoil by approximately 30% compared to straight blowback designs. The system cycles more smoothly than traditional pistol-caliber carbines while accepting standard Glock magazines. This engineering approach delivers consistent ejection patterns and reduces bolt face wear over extended firing sessions.

Key Features

• Radial delayed blowback system with enhanced recoil management
• 8-inch medium taper barrel with 1/2x28 threading for suppressors
• 7-inch EML M-LOK handguard with multiple attachment points
• Black Armor Cerakote finish rated for 2,400+ hours salt spray resistance
• Ambidextrous controls including safety selector and magazine release
• CMMG Zeroed linear compensator reduces muzzle blast
• Accepts standard Glock 22/23 magazines up to 22-round capacity

The Banshee excels in close-quarters applications where maneuverability matters. Law enforcement agencies report improved accuracy in vehicle operations due to the reduced overall length. The threaded barrel accommodates sound suppressors without requiring additional modifications. Weather sealing at critical junctions maintains function in adverse conditions, with documented operation from -20°F to 140°F.
