CMMG Inc. · Personal Defense Weapon · In Production · 2019
Also known as: Banshee Mk9 RDB, Banshee 300 Mk9, CMMG Mk9
Overview
The CMMG Banshee Mk9 is a compact 9mm AR-platform pistol-caliber personal defense weapon (PDW) built on CMMG's patented Radial Delayed Blowback operating system, which uses a rotating, radially-lugged bolt to slow the initial opening of the action and dramatically soften felt recoil compared with the straight blowback design it replaced. The Mk9 is distinguished within the Banshee line by a dedicated magazine well that accepts Colt SMG-pattern 9mm stick magazines in 10-, 20-, and 32-round capacities. It is offered as a braced pistol or short-barreled rifle with a 5-inch or 8-inch barrel, paired with a forged 7075-T6 aluminum upper, an M-LOK handguard, an oversized ambidextrous charging handle, and last-round bolt-hold-open.
