The CMMG Banshee Mk4 .22 LR is a compact, purpose-built rimfire pistol that delivers fun, low-recoil shooting without the price tag of centerfire ammo. At just 4.5 inches of barrel, this is CMMG's shortest Banshee offering—perfect for shooters who want a handy plinker, training platform, or backyard shooter that won't break the bank to run. At 4.2 lbs and 19.9 inches overall, it's light and maneuverable, making it an ideal choice for new shooters, competitive trainers, or anyone who values affordable, high-round-count practice.

Built on the proven Mk4 platform with traditional blowback operation, the Banshee Mk4 combines modular AR ergonomics with .22 LR reliability. The billet upper and forged lower receiver ensure durability, while the M-LOK handguard keeps the gun nimble and accessory-ready if you want to add optics or lighting down the road. The trigger is a CMMG ZEROED drop-in single-stage unit—crisp and predictable right out of the box. Ambidextrous controls (charging handle and safety selector) and the RipBrace mean both left and right-hand shooters can operate it naturally.

The 1:16 twist rate and MT contour barrel are optimized for .22 LR ballistics, while the CMMG ZEROED flash hider with 1/2 x 28 threads keeps the muzzle signature minimal. Twenty-five-round magazines keep you shooting longer between reloads. Cerakote finish in Armor Black resists wear and corrosion. Whether you're teaching new shooters, running drills, or just ringing steel for fun, the Banshee Mk4 .22 LR offers the handling and modularity of an AR platform without the noise, recoil, or ammo costs of centerfire.
