CMMG 30AF20ACT Banshee Mk4 300 Blackout 30+1 8″ Black Nitride Threaded Barrel, M-LOK Handguard, Coyote Tan Cerakote Aluminum Receiver w/Picatinny Rail, Black Polymer CMMG RipBrace, CMMG Zeroed Grip
The CMMG Banshee Mk4 is a compact AR-pattern pistol built around an 8-inch nitride-threaded barrel and an M-LOK handguard for modular accessory mounting. The package emphasizes a ready-to-use parts kit with CMMG’s ZEROED components and a coyote-tan Cerakote finish on the aluminum receiver. Its configuration favors short-barrel, suppressed, and close-range use where maneuverability and modularity matter.
Suggested optic: a red-dot such as the Holosun HS503CU pairs well for fast target acquisition on this platform and stays well under common upper-tier optic budgets. Typical applications include short-range precision shooting and suppressed/subsonic training with stabilized ammunition.

The Banshee Mk4 is purpose-built for shooters who want an immediately usable AR-pattern pistol with a substantial kit of factory ZEROED components. Its short barrel and modular handguard make it easy to mount lights, offsets, or a compact red dot and run a suppressed or subsonic configuration where legal and appropriate. The combination of an aluminum receiver, durable Cerakote finish, and a nitride-threaded barrel gives a balanced blend of corrosion resistance and serviceability for range and training use.
Owners commonly praise the included ZEROED parts and the overall build quality as standout features of this package.
