Shooters consistently report tight groupings and reliable feeding with both supersonic and subsonic .300 Blackout loads. The tungsten Cerakote finish on this AR pistol provides exceptional corrosion resistance and durability in harsh shooting environments. CMMG’s quality control ensures that each Banshee MK4 passes rigorous testing before leaving the factory, guaranteeing reliability from day one. The ambidextrous controls allow left and right-handed shooters to operate the firearm intuitively without modification. Whether you’re running 200-grain subsonic ammunition for suppressed fire or 110-grain supersonic loads for maximum velocity, the CMMG Banshee MK4 .300 Blackout handles both with consistent performance. The included pistol stabilizing brace enhances control and accuracy while maintaining the legal classification as a pistol. The 5/8X24 threaded barrel allows for easy attachment of suppressors, flash hiders, or other muzzle devices to customize the platform further. The 30-round magazine capacity provides ample ammunition for extended shooting sessions without frequent reloads.
