Design and Key Features

CMMG BANSHEE MK4 pairs a 12.5″ cold‑hammer‑forged barrel with a compact pistol receiver to keep overall length minimal while preserving effective accuracy out to typical engagement distances. The Armor Black finish resists corrosion and reduces signature. The package follows Cmmg’s reputation for reliable semi-auto systems and comes in various model configurations, allowing shooters to prioritize suppressor readiness or a lighter, non‑suppressed setup.

Why .300 Blackout?

The .300 Blackout caliber excels in short barrels and behind suppressors. With a 12.5″ barrel, it delivers strong terminal energy with supersonic loads and optimized subsonic performance for suppressed use. For home defense and tactical teams, that flexibility—combined with compact handling—makes the caliber and barrel length pairing particularly effective.

Performance and Handling

Expect quick transitions and controllable recoil from the MK4 platform. The shorter barrel reduces moment of inertia, improving agility in close quarters. Controls are user-friendly for rapid follow-up shots, and the semi-auto action cycles a broad range of factory and handloaded .300 Blackout ammunition when properly maintained.
