Compact, reliable, and built for tactical accuracy, modern short-barrel platforms demand careful balance between maneuverability and controllability. Operators and enthusiasts looking for a rifle capable in both suppressed subsonic roles and hard-hitting supersonic work need components engineered for those specific demands.

CMMG BANSHEE MK4 brings that balance to life with a purpose-built .300 Blackout configuration that emphasizes short-barrel performance and modular utility.

Key features and hardware

The platform ships with an 8″ Black Nitride medium taper threaded barrel rated for 30+1 capacity, making it optimized for both suppressed subsonic and supersonic loads. Its EML 7″ M-LOK handguards include full-length M-LOK slots on the sides and bottom, plus M-LOK between the top Picatinny rail sections for accessory flexibility.

ZEROED component set

This model arrives with a comprehensive ZEROED parts package: pistol grip, drop-in trigger, 60/90 degree ambidextrous safety, linear compensator, ambi mag catch, extended mag release button, ambi charging handle, bolt catch and polymer dust cover. That level of factory-installed ergonomics reduces setup time and ensures consistent, user-ready operation.

Receiver and magazine

The Black Armor Cerakote aluminum Picatinny rail receiver provides a durable mounting platform for optics and backup sights. The rifle ships with a 30-round PMAG included, providing immediate capacity for training or duty applications.
