CMMG BNSHE MK4 300BLK 8″ PB 30RD MB

Description

The CMMG Banshee Mk4 is built for shooters who want a compact, suppressor-ready pistol that handles both subsonic and supersonic .300 Blackout without compromise. The 8-inch barrel keeps the overall package short and maneuverable while still extracting meaningful velocity from the cartridge — a balance that matters more in .300 Blackout than in most chamberings, since the round was designed from the outset to function reliably even at the reduced gas pressures a short barrel produces. That makes this platform a natural fit for suppressed shooting, where subsonic loads and a can combine to reduce the report significantly without requiring any manual intervention to cycle the action.

CMMG equips the Mk4 with their EML handguard, which runs full-length M-LOK slots along the sides and bottom and transitions to Picatinny rail sections at the top. That arrangement keeps weight down while giving you a clean rail for a light or foregrip and a top rail for optics without requiring additional hardware. The handguard is optics-ready out of the box, so whatever magnified or red-dot optic suits your use case mounts directly without riser adapters.

The ZEROED component set — which includes a drop-in trigger, pistol grip, and 60/90-degree ambidextrous safety — means the controls are configured for either hand without modification. The ambidextrous charging handle, bolt catch, and magazine release extend that symmetry through every manipulation. An integrated linear compensator directs muzzle blast forward rather than to the sides, which matters in close-quarters environments. The pistol ships with a single 30-round PMAG. Finish is Midnight Bronze.
