Primary Weapons UXR Elite .308 Winchester Semi Auto Rifle - Blue/Black, 16" Barrel, 30+1 Rounds, 6-Position Black Stock

The proprietary UXR, or User XChange Rifle, is the pinnacle of firearm innovation. This revolutionary system offers unmatched modularity and performance. The patent-pending XCHANGE system allows the shooter to quickly convert to alternate calibers on the same serialized platform by exchanging just three parts - the magazine well, bolt head and barrel. To create an unparalleled shooting experience, the proprietary UXR introduces a unique bore-evacuation chamber incorporated into the barrel, along with a modified long-stroke piston system, which together allow for a smoother shot and lower recoil.
