The CMMG BNSHE MK4 9MM 5" FE PB 30RD TG takes the proven Mk4 AR platform and shrinks it into the most compact 9mm BANSHEE configuration CMMG makes, delivering a 5" threaded barrel, Cerakote Tungsten finish, and a pistol brace for maneuverable semi-automatic performance in close-quarters, home defense, and range training. Youll notice the ZEROED drop-in single stage trigger for a crisp pull, ZEROED ambidextrous mag catch, charging handle and safety for true left- or right-hand operation, and a ZEROED extended mag release button that speeds reloads under stress; the radial delayed blowback system smooths recoil impulse for faster follow-up shots, and the threaded barrel pairs with the included ZEROED linear compensator if you want to tune muzzle rise or add a suppressor where legal. As an AR-format 9mm Luger, the MK4 accepts CMMG 9mm conversion mags and mounts optics easily with its optics-ready top, making it a versatile pistol for competition, duty use, or a compact truck gun. Built from aluminum with polymer grips and styled in Tungsten Cerakote, this model requires an FFL transfer and adheres to state and local restrictions where applicable, while delivering the compact handling, 30-round capacity, and modular features buyers look for in a modern 9mm AR pistol.
