The CMMG Banshee line of AR pistols come in a wide variety of barrel lengths, calibers, and accessories, so you can find the right one for the job. The Banshee 200 MkGs is chambered in 9mm and designed to be compatible with the ever popular Glock magazines. It utilizes a simple radial delayed blowback system which helps to completely negate the sharp recoil of a standard blowback system. It also allows the use of a lighter bolt, so there is less mass slamming back and forth resulting in lighter felt recoil, less parts wear, and better reliability. No need for a gas block or gas tube, this extremely simple and effective set-up is perfect for 9mm pistol caliber AR-15s. The barrel is made from 4140 steel and salt bath Nitride finished for extreme durability. The 7” RML handguard features M-LOK slots for attaching accessories and features a top picatinny rail that sits flush with the flat top upper receiver. The CMMG MkGs Banshee 200 AR-15 pistol is a compact package that shoots highly available and affordable 9mm ammo.

This custom lower receiver also features an integral trigger guard and comes with a CMMG single stage Mil-Spec trigger. Outfitted with a Magpul MOE pistol grip and the RipBrace, this pistol is extremely ergonomic and comfortable to shoot. Compatible with aftermarket AR-15 parts like the charging handle, safety selector, dust cover, and takedown pins, you can add a little flair to your CMMG MkGs pistol.
