CMMG Banshee MK4 5.56x45mm 12.5" 30+1 Semi-Auto AR Pistol

The CMMG Banshee MK4 is a 5.56x45mm NATO semi-automatic AR pistol built on CMMG's modular Mk4 platform. Designed to deliver rifle-caliber performance in a compact, maneuverable package, the Banshee MK4 is well suited for home defense, range use, and as a feature-rich base for further customization.

At the heart of this pistol is a 12.50" medium-taper threaded barrel finished in black nitride for enhanced durability and corrosion resistance. The barrel is paired with CMMG's EML 11" M-LOK handguard, providing a full-length M-LOK attachment system for accessories while keeping the overall footprint compact and balanced.

The aluminum receiver wears a Black Armor Cerakote finish and is topped with a Picatinny rail for optics and accessory mounting. CMMG Zeroed grips offer an ergonomic hold, while the CMMG Zeroed 60/90 degree ambidextrous safety selector provides configurable, intuitive operation. This model ships with no iron sights, allowing the shooter to outfit the platform with their preferred optic.

With a 30+1 capacity, the Banshee MK4 ships with one 30-round Magpul magazine so you can hit the range or build out a defensive loadout right away. Whether you are after a compact AR pistol platform or a reliable companion for recreational and defensive shooting, the CMMG Banshee MK4 delivers the quality and modularity CMMG is known for.
