CMMG Banshee MK4 22LR 9" Barrel Tube Stock AR Black Pistol

The CMMG Banshee MK4 in 22LR transforms rimfire training and plinking with AR-15 ergonomics and proven radial delayed blowback operation. This 9-inch barreled pistol delivers centerfire handling characteristics while maintaining the affordability and low recoil of 22 Long Rifle ammunition.

What Makes This Different

Unlike direct blowback 22LR conversions, the Banshee MK4 utilizes CMMG's proprietary radial delayed blowback system that cycles reliably with standard velocity ammunition. The system reduces bolt velocity and felt recoil compared to straight blowback designs while maintaining consistent ejection patterns. This dedicated 22LR platform eliminates the compromises found in conversion kits or adapted centerfire actions.

Key Features

• Radial delayed blowback action optimized specifically for 22LR ammunition
• 9-inch 4140 chrome moly steel barrel with 1:16 twist rate
• Tube-style buffer system designed for pistol configuration
• Standard AR-15 trigger group compatibility and ergonomics
• Picatinny rail system for optics and accessory mounting
• Last round bolt hold open functionality
• Compatible with most AR-15 aftermarket triggers and furniture

The Banshee MK4 excels in training applications where shooters want to maintain AR-15 muscle memory while reducing ammunition costs. Competition shooters appreciate the consistent cycling and accuracy potential for rimfire divisions. The compact 9-inch configuration balances maneuverability with ballistic performance, making it suitable for both indoor ranges and field use. Weather-resistant finishes and quality construction ensure reliable function across temperature ranges.
