The .300 Blackout excels when suppressed—subsonic loads remain subsonic throughout their flight, delivering effective terminal performance without the supersonic crack. The Banshee MK4's compact profile, ambidextrous controls, and modular M-LOK system make it equally at home in the hands of tactical professionals and serious sport shooters. Whether you're building a suppressed home-defense platform or a precision subsonic rifle, the Banshee MK4 delivers.
