Radian Weapons Model 1 Features The Radian Weapons Model 1 s Dead Air Keymo flash hider is pinned and welded to the match-grade barrel extending it to a legal 16 inch overall length while managing flash and recoil and the direct impingement operating system keeps the rifle running reliably with the Radian Vertex trigger providing a clean repeatable break. A Picatinny rail atop the receiver gives shooters a solid mounting surface for optics. The Magpul DT-PR stock and Black Magpul K2 grip give the Model 1 a refined ergonomic feel and the ambidextrous safety lever keeps controls accessible regardless of shooting hand. Every rifle is hand-assembled and cleaned by a trained gunsmith before it leaves the factory reflecting Radian s commitment to quality and consistency. For shooters who want a precision-focused hand-built AR chambered in the efficient 6mm ARC cartridge the Model 1 is available for sale at GrabAGun.
