The CMMG Banshee MkGs 300 Blackout delivers compact firepower in a pistol-format platform engineered for versatility and reliability. This radial delayed blowback system operates without a traditional gas system, reducing weight while maintaining consistent cycling across subsonic and supersonic ammunition.
What Makes This Different
The Banshee MkGs utilizes CMMG's proven radial delayed blowback operating system instead of direct impingement or piston operation. This design eliminates the need for a gas block and tube, creating a cleaner-running firearm with reduced fouling in the action. The system cycles reliably with both subsonic and supersonic 300 Blackout loads, making it ideal for suppressed or unsuppressed use.Key Features
