The CMMG Banshee MK4 in 300 Blackout delivers compact firepower with an 8-inch barrel optimized for close-quarters performance. This AR-platform pistol combines CMMG's proven engineering with the versatility of 300 BLK ammunition for both subsonic and supersonic applications.
What Makes This Different
Built on CMMG's proprietary MK4 lower receiver, this Banshee features a radial delayed blowback operating system that reduces felt recoil and improves reliability with both supersonic and subsonic 300 Blackout loads. The system requires no gas block or gas tube, simplifying maintenance while delivering consistent cycling across various ammunition weights. The compact 8-inch barrel maintains effective terminal ballistics within 200 yards while keeping overall length manageable for vehicle use or confined spaces.Key Features
