Cmmg Banshee Mk4 22Lr 9 Armor Black

The CMMG Banshee Mk4 in .22 LR is a purpose-built AR pistol that makes affordable range training and fun shooting accessible without compromising on controls, ergonomics, or platform familiarity. Built on CMMG's proven Mk4 platform, this 9-inch barreled .22 LR operates via traditional blowback and delivers the handling of an AR-15 in a compact, light package. At just 4.9 lbs and 24.7 inches overall, it's nimble enough for shooters who want to practice precision fundamentals, introduce newer shooters to AR-platform operation, or simply enjoy high-volume range days without the recoil or ammunition cost of centerfire options.

CMMG equipped this Banshee with quality components throughout: a billet upper receiver in 6061 T6 aluminum paired with a forged Mk4 lower in 7075 T6 aluminum for lasting durability. The 9-inch barrel wears a CMMG ZEROED flash hider and is threaded 1/2 x 28 for suppressors and other muzzle devices. The EML7 M-LOK hand guard gives you modular mounting options, while the RipBrace provides stable support and is tuned to the .22 LR platform. Controls are ambidextrous where it counts—the charging handle and safety selector (60/90 degree) work from either side—and the ZEROED drop-in single-stage trigger and trigger guard make it easy to tailor the gun to your preference.

The included 25-round magazine lets you shoot longer strings before reloading, and the Cerakote finish on that Armor Black anodized receiver stands up to range use and hard handling. Whether you're breaking in a new shooter, maintaining trigger control during off-season training, or just having fun without the expense of centerfire ammunition, the Banshee Mk4 .22 LR is a versatile, approachable choice that doesn't ask you to compromise on AR-platform handling or build quality.
