The CMMG Banshee MKGs is a compact 9mm AR pistol built for shooters who want serious capability in a maneuverable package. At just 20.8 inches long and 4.5 pounds, this is one of CMMG's most portable AR platforms—ideal for home defense, truck gun duty, or anyone who values a short, handy rifle that doesn't sacrifice reliability. The fixed ejector system with radial delayed blowback operation feeds from Glock-pattern double-stack magazines (33-round capacity), so ammo compatibility and magazine sourcing are never a problem.
Built on the MKGs platform, the Banshee pairs a 5-inch nitride-finished barrel with a CMMG ZEROED linear compensator to keep muzzle rise manageable in a short format. The upper is billed 6061 T6 aluminum; the lower is forged 7075 T6—tough enough for hard use. The EML4 M-LOK handguard gives you mounting options at 3, 6, and 9 o'clock, plus a full-length Picatinny rail on top for optics and accessories. An integrated handstop keeps your grip consistent.
The Midnight Bronze Cerakote finish looks sharp and resists wear. You get a CMMG ZEROED drop-in single-stage trigger, ambidextrous charging handle, and the quick-deploying RipBrace for stable, controllable shooting. The 60/90-degree safety selector and integrated trigger guard round out a platform that's as practical as it is compact. Whether you're running it suppressed, setting it up as a truck gun, or keeping it home for personal defense, the Banshee MKGs delivers AR reliability in a form factor that fits tight spaces.

The Banshee MKGs is designed around Glock-pattern double-stack magazines and ships with a 33-round capacity magazine. Any standard Glock 9mm magazine will work, giving you plenty of options for sourcing ammunition and spares.
Yes. At 20.8 inches overall and 4.5 pounds, it's one of CMMG's most compact AR platforms. The short barrel, maneuverable profile, and RipBrace make it well-suited for home defense, vehicle storage, or any scenario where you need a reliable, controllable 9mm rifle in a tight space.
The barrel is threaded 1/2 x 28, which is standard for 9mm suppressors. You can absolutely run it suppressed, making it an excellent platform for quiet, low-recoil shooting if you have the proper tax stamp and local compliance.
The CMMG RipBrace is integrated into this model and is designed for quick deployment and stable shooting control. It provides the brace support needed for one-handed or two-handed firing while keeping the platform compact and controllable.
