The BansheeTM 300 MkGs Upper Group Kit fits on most standard AR-15 lowers to create a premium 9mm AR pistol. The Banshee 300 Upper Kit comes complete with a 5" stainless steel barrel and CMMG's own Radial Delayed Blowback bolt carrier group. Unlike typical blowback systems, Radial Delayed Blowback not only reduces the weight in your BCG, it also reduces felt recoil—allowing you to stay on target and make faster follow-up shots.

The RML4 4" M-LOK handguard accepts any number of modern accessories, and the full-length Picatinny top rail allows for versatile optics placement. The upper itself is a standard forged 7075-T6 M4-style upper, but comes equipped with CMMG's oversized ambidextrous charging handle for easy charging. Completing the package are (3) 30-rd. AR conversion magazines made specifically for the 9mm cartridge, giving you plenty of firepower.
