The Primary Weapons UXR-CK-762X39-14 UXR Conversion Kit transforms your PWS UXR platform into a 7.62x39mm performer with a compact 14.5" barrel. Built around the innovative UXR (User XChange Rifle) system, this kit leverages XCHANGE technology so you can swap calibers by changing only the magazine well, bolt head, and barrel, maintaining a familiar, consistent shooting experience.

This 7.62x39mm conversion is ideal for shooters who want to take advantage of widely available ammunition while keeping the same UXR Elite rifle system. The included barrel and bolt are engineered for smooth operation, with a bore-evacuation chamber and a refined long-stroke piston system that help reduce recoil and keep shots controllable over extended strings of fire. Whether you are focused on range training, practical drills, or general-purpose shooting, this kit adds meaningful versatility to your existing UXR while reflecting Primary Weapons’ commitment to modularity and innovation.
