CMMG Banshee Mk4 .300 Blackout - 1x 30 Round Magazine - 12.5" - Pistol

The CMMG Banshee Mk4 in .300 Blackout is the 12.5-inch RipBrace configuration — a purpose-built .300 BLK AR pistol that ships ready to run with a full ZEROED accessories package, CMMG RipBrace, and one 30-round Magpul PMAG. .300 BLK was engineered from day one for short-barrel and suppressed AR applications, and the Banshee Mk4's 12.5-inch barrel with 5/8x24 threaded muzzle is the ideal length to maximize the cartridge's supersonic and subsonic performance.

The CMMG Banshee Mk4 is a semi-automatic pistol chambered in .300 Blackout, built on a billet 6061 T6 aluminum upper receiver and forged 7075 T6 aluminum Mk4 lower receiver in black Armor Cerakote with a 12.5-inch 4140 chrome moly black nitride medium taper barrel and direct impingement operating system.

The full ZEROED accessories package ships installed: ZEROED drop-in single stage trigger, ZEROED pistol grip, ZEROED 60/90-degree ambidextrous safety selector, ZEROED ambidextrous charging handle, ZEROED trigger guard, and ZEROED Linear Compensator — a comprehensive upgrade over mil-spec components that requires no additional investment. The CMMG RipBrace deploys quickly from its folded position with a single motion, providing an adjustable brace for additional stability and control without NFA requirements. The 7-inch EML M-LOK handguard features full-length M-LOK slots on the 3, 6, and 9 o'clock positions plus M-LOK slots between the top Picatinny rail sections for maximum accessory mounting flexibility. The 1:7 right-hand twist barrel stabilizes all .300 BLK projectile weights reliably, from 110-grain supersonic to 220-grain subsonic. The 5/8x24 threaded muzzle accepts suppressors with the compensator removed. One 30-round Magpul PMAG is included. Backed by CMMG's Lifetime Quality Guarantee.
