CMMG 30AF20AMB Banshee MK4 .300 Blackout 8" 31-Round Threaded Barrel Pistol

The CMMG 30AF20AMB Banshee MK4 .300 Blackout 8" 31-round threaded barrel pistol is purpose-built for tactical professionals, law enforcement, and serious shooters who demand a compact, magazine-fed platform optimized for subsonic performance and suppressed fire. This is a short-barreled rifle (SBR) pistol configuration designed for close-quarters operations, dynamic room clearing, and specialized tactical deployments where velocity and accuracy matter at intermediate distances. The Banshee platform has proven itself across military and law enforcement units, offering reliability and modularity in an ergonomic package that transitions seamlessly between mounted optics and iron sights.

The 8-inch barrel in .300 Blackout delivers optimal velocity for subsonic ammunition while maintaining inherent accuracy benefits of a direct-impingement system refined through generations of combat rifle design. The threaded barrel accepts standard suppressors and muzzle devices without adapters, enabling silent operation critical to tactical missions and specialized training where noise discipline protects operational security. At 4 pounds, the platform achieves lightweight handling without sacrificing the 31-round capacity that provides sustained firepower and extended engagement capability; this weight distribution enhances target acquisition speed and reduces shooter fatigue during extended operations. The compact 13.5-inch overall length with the 8-inch barrel creates a maneuverable profile ideal for vehicle operations, breaching scenarios, and confined spaces where full-length rifles prove unwieldy.

End-users from tactical teams, special operations units, and precision rifle competitors benefit from the Banshee platform's proven track record and aftermarket ecosystem that supports caliber conversions and upper receiver configurations. The threaded barrel directly accepts industry-standard suppressors with 1/2x28 pitch, unlocking the full potential of .300 Blackout's subsonic design without additional hardware. Operators integrating this platform should verify local and federal compliance regarding SBR registration and suppressor legality in their jurisdiction; registration of short-barreled rifles is federally mandated under the National Firearms Act. The 31-round magazine capacity pairs effectively with both suppressed and unsuppressed configurations, offering tactical flexibility for training, defensive deployment, and specialized precision applications.
