The CMMG Banshee Mk4 Pistol (brand part no. 94AD90F-TNG) pushes CMMG’s proven Mk4 AR-15 platform to its most compact 9mm configuration yet, with a 5-inch barrel that’s the shortest offered in the Banshee lineup. Chambered in 9mm and built around CMMG’s conversion magazine system, this pistol trades barrel length for an extremely short, easy-to-maneuver package well suited to home defense or a dedicated close-quarters build. It ships optics-ready with an ambidextrous safety and a 30-round magazine. It’s the most compact pistol-caliber option in the AR pistols lineup from CMMG.
