The CMMG Banshee MK4 delivers compact firepower in 300 Blackout with a 12.5-inch barrel optimized for both supersonic and subsonic ammunition. This pistol configuration combines CMMG's radial delayed blowback system with premium components for reliable cycling across the full range of 300 BLK loadings.
What Makes This Different
CMMG's radial delayed blowback operating system eliminates the need for a buffer tube, enabling true pistol configurations while maintaining consistent ejection patterns. The system runs cleaner than direct impingement designs and cycles reliably with loads from 110-grain supersonic to 220-grain subsonic. This translates to fewer malfunctions and simplified maintenance compared to standard AR-15 pattern firearms.Key Features
