The CMMG Banshee MK4: Compact Power in .300 Blackout

The Banshee MK4 represents CMMG's commitment to delivering a purpose-built platform for modern shooting applications. Chambered in .300 Blackout, this compact pistol excels whether you're running subsonic ammunition through a suppressor or pushing supersonic loads downrange.

Design and Ergonomics

Fully ambidextrous controls define this platform. The Banshee MK4 features:

  • Ambi safety with 60/90-degree positions for both left and right-handed shooters
  • Ambi charging handle for rapid manipulation from either side
  • Ambi magazine catch and extended mag release button
  • ZEROED pistol grip optimized for control and comfort

Handguard and Mounting

The 7-inch EML handguard provides extensive mounting options with full-length M-LOK slots on both sides and bottom, plus M-LOK sections between top Picatinny rail sections. This gives you flexibility to mount lights, lasers, or other accessories exactly where you need them.

Barrel and Accuracy

The 8-inch, 5/8x24 threaded barrel is medium-taper profile and finished in black nitride. This length balances velocity with maneuverability, making it ideal for close-quarters work or suppressed applications.

Included Components

Each Banshee MK4 ships with a 30-round PMAG magazine and features CMMG's ZEROED drop-in trigger, linear compensator, bolt catch, and polymer dust cover. The Black Armor Cerakote aluminum receiver provides durability and corrosion resistance.

The .300 Blackout Advantage

Originally designed for short-barrel rifles and suppressors, .300 Blackout has proven itself as a versatile intermediate cartridge. It delivers rifle-class power in a compact package, making it an excellent choice for home defense, tactical training, or recreational shooting.
