CMMG Banshee MK4 300 Blackout 8" 30+1 Semi-Auto AR Pistol - Midnight Bronze Cerakote

The CMMG Banshee MK4 is a compact semi-auto AR-platform pistol chambered in 300 Blackout, purpose-built around CMMG's Mk4 platform for optimum performance in subsonic, suppressed, and short-barrel applications. An 8" medium-taper threaded barrel finished in black nitride and a svelte 23.70" overall length keep the platform small and quick-handling while still offering 30+1 capacity from a standard AR-pattern magazine.

At the core of this pistol is CMMG's Mk4 architecture - the company's dedicated 300 Blackout platform designed to optimize performance with both subsonic and supersonic loads. The barrel is an 8" medium-taper profile with a threaded muzzle ready for suppressor or muzzle-device attachment, finished in black nitride for durability and corrosion resistance. The receiver is finished in Midnight Bronze Cerakote over an aluminum upper with a full-length Picatinny rail, giving shooters a ready-made optics mounting platform straight out of the box.

The handguard is CMMG's EML 7" M-LOK design, with M-LOK slots along both sides and the bottom plus additional M-LOK compatibility between the top Picatinny rail sections for flexible accessory mounting. The pistol is fitted with CMMG Zeroed grips and a CMMG Zeroed 60/90 degree ambidextrous safety, continuing the Zeroed accessory family for an out-of-the-box-ready control layout. No sights are included, allowing the shooter to pair the optic or iron setup of their choice with the integrated Picatinny rail.

Tipped in at just 4.70 lbs, the Banshee MK4 300 Blackout is a lightweight, compact platform equally at home on a subsonic suppressor build or as a short, fast-handling defensive pistol. The 300 Blackout cartridge delivers .30-caliber ballistics from short barrels and pairs naturally with the Mk4's design intent, making this Banshee a versatile addition to any collection.
