CMMG Banshee Mk4 300 Blackout | 30AF20ATNG | 8″

Compact and purpose-built, the CMMG Banshee Mk4 in .300 AAC Blackout provides an AR-pattern pistol platform optimized for short-barrel and suppressed use. This configuration ships with an 8″ black nitride threaded barrel, M-LOK handguard and a tungsten-toned Cerakote aluminum receiver, and it accepts standard AR controls and magazines. For this platform a low-power variable optic like a Vortex Strike Eagle 1-6×24 offers useful magnification for short-range precision while remaining rugged and under $1,000.

Typical applications include precision short-range shooting and suppressed or subsonic training. The compact length and pistol brace also make it well-suited for use as a portable range or patrol-style training tool.
