CMMG Banshee MK4 300 Blackout 8" Barrel 30rd Midnight Bronze

The CMMG Banshee MK4 in 300 Blackout delivers compact firepower with an 8-inch black nitride barrel and midnight bronze Cerakote finish. This AR-15 style pistol combines CMMG's proven radial delayed blowback system with premium components for reliable performance in close-quarters applications.

What Makes This Different

Unlike direct impingement systems, the Banshee MK4 uses CMMG's radial delayed blowback operation that runs cleaner and requires less maintenance. The medium taper barrel profile balances weight reduction with heat dissipation. The EML 7-inch M-LOK handguard provides ample mounting space while keeping overall length compact at just 15.5 inches collapsed.

Key Features

• Radial delayed blowback system eliminates gas tube reliability issues
• 8-inch black nitride barrel with 1:7 twist rate and threaded muzzle
• 30-round magazine capacity with last round bolt hold open
• Midnight bronze Cerakote aluminum receiver with Picatinny rail
• EML 7-inch M-LOK handguard for accessories and optics mounting
• CMMG Zeroed ambidextrous safety selector and pistol grip
• SB Tactical SBA3 adjustable pistol brace included

The 300 Blackout cartridge excels in suppressed applications and close-range scenarios where the Banshee's compact dimensions shine. The radial delayed system cycles both supersonic and subsonic ammunition reliably without gas system adjustments. Accuracy typically runs 2-3 MOA with quality ammunition, making it effective for home defense and tactical applications within 200 yards.
