CMMG® Banshee Mk4 .300 AAC Blackout Semi-automatic AR Pistol

The Banshee Mk4 is CMMG’s top-of-the-line AR Pistol, featuring premium American-made components across the board for quality you can count on. It comes equipped with CMMG’s own RipBrace stabilizing brace, which features FastBack technology for rapid deployment: just pull it straight back to deploy it. There are no locking tabs to bind, and an indexing screw lets you pre-set your desired length.

The Banshee features CMMG’s ZEROED components front to back. ZEROED components are American-made to deliver a much higher level of performance than standard mil-spec. The new EML 7″ handguard provides outstanding stability without unnecessary weight. M-LOK attachment slots are found where expected at the 3, 6, and 9 o’clock positions, as well as on top at 12 o’clock position with the omission of a full-length Picatinny section found on CMMG’s previous handguard. This reduces weight while giving you plenty of real estate to mount those must-have accessories.
