CMMG 30AF20ATNG Banshee Mk4 .300 Blackout 8" 31-Round Threaded Barrel Rifle

The CMMG 30AF20ATNG Banshee Mk4 .300 Blackout 8" 31-Round Threaded Barrel Rifle is purpose-built for close-quarters tactical operations, home defense, and specialized law enforcement applications where short barrel performance and subsonic ammunition compatibility are mission-critical. Developed for operators who require suppressed firepower without sacrificing reliability or ergonomics, this platform delivers the ballistic advantages of .300 Blackout in a compact form factor suitable for vehicle operations, building clearance, and precision work in confined environments.

The 8-inch barrel is threaded (1/2x28) for direct-thread or adapter-based suppressor installation, allowing full-spectrum use of subsonic .300 Blackout ammunition while maintaining hearing-safe operation and minimal muzzle signature—essential for tactical deployments. The Banshee Mk4's modular design leverages CMMG's proprietary carrier system and features a 31-round magazine capacity for sustained engagement capability. At 10.14 lbs fully assembled, the rifle balances controllability with sufficient mass for recoil management and accessory mounting, while the compact 13.8-inch overall length—with collapsed or pinned stock—enables swift maneuverability in vehicle, building, and CQB scenarios typical of tactical service.

This platform is ideal for special operations personnel, experienced defensive shooters, and law enforcement teams operating under NFA guidelines who demand a reliable, suppression-ready .300 Blackout rifle for specialized missions. The threaded barrel accommodates industry-standard suppressors, and the modular receiver and ergonomic controls support tactical lighting, red-dot or magnified optics, and pressure switches without modification. Compliance with local, state, and federal firearms regulations—including NFA registration for suppressed configurations—remains the end-user's responsibility.
