CMMG Banshee MKGs 9mm | 5″ | 33rd | 99A290F-AB

The CMMG Banshee MKGs is a compact 9mm AR-style pistol built around the MkGs platform and supplied with a 33-round double-stack Glock-pattern magazine and a RipBrace pistol brace. It uses a fixed-ejector radial delayed blowback operating system and includes AR-standard features such as an M-LOK handguard and ambidextrous controls. The 5″ threaded barrel and compact overall length make it suitable where a short, pistol-configured carbine is desired. Pair this pistol with a compact red-dot optic such as the Vortex Venom for fast target acquisition within practical pistol-caliber ranges.

Recommended use includes range training and pistol-caliber carbine (PCC) competition or tactical carbine-style practice.
