CMMG Banshee Mk4 300 Blackout Pistol 8" Coyote Tan

The CMMG Banshee Mk4: Purpose-Built for Modern Shooting

The Banshee Mk4 represents a thoughtful evolution in short-barrel rifle design. Chambered in 300 Blackout—a cartridge specifically engineered for subsonic, suppressed, and short-barrel applications—this platform delivers genuine capability in a compact package.

Why This Platform Works

The 300 Blackout cartridge was purpose-designed for short barrels. Unlike 5.56 NATO, which loses significant velocity in compact configurations, 300 Blackout maintains its intended performance characteristics. Pair this with the Banshee's compact footprint and modular design, and you have a firearm equally at home for home defense, tactical training, or suppressed shooting.

The Coyote Tan finish provides both aesthetic appeal and practical concealment in varied environments.
