CMMG Banshee MK4 300 BLK 8" - AR-15 Pistol - 1x 30rd Mag - Midnight Bronze

The compact versatility of 300 Blackout pairs with CMMG’s refined platform engineering in the Banshee MK4. Whether running supersonic rounds for maximum velocity or cycling subsonic loads through a suppressor, this pistol delivers the full ballistic range of the 300 BLK cartridge in a short-barreled, manageable package.

The CMMG Banshee MK4 is a direct impingement AR-style pistol chambered in 300 Blackout, built around an 8-inch chrome moly steel barrel with a black nitride finish and a Midnight Bronze Cerakote aluminum receiver.

The 8-inch barrel maintains useful 300 BLK velocity at close- to mid-range distances while keeping the overall footprint compact. A 7-inch EML M-LOK handguard provides substantial rail space for lights, grips, and accessories without adding unnecessary bulk. The CMMG Zeroed Linear Compensator threaded onto the 1/2x28 muzzle reduces felt concussion when shooting unsuppressed, and the Zeroed Drop-In Single Stage trigger delivers a crisp, consistent pull. A CMMG 6-Position RipBrace rounds out the package.

The 1/2x28 threaded muzzle accommodates 300 BLK-rated suppressors and compensators. The 1:7 twist rate stabilizes a broad range of projectile weights, and standard AR-15 magazines feed reliably from the lower.

The chrome moly steel barrel with black nitride finish provides corrosion resistance and sustained durability through hard use. The aluminum receiver finished in Midnight Bronze Cerakote adds weather resistance alongside its distinctive appearance.

An effective choice as a suppressor host, home defense platform, or range pistol, the Banshee MK4 packages the 300 BLK cartridge’s versatility into a pistol-format footprint that handles well in confined spaces.
