The proprietary UXR or User XChange Rifle, redefines firearm innovation with a groundbreaking design that delivers exceptional modularity and performance. Its patent-pending XCHANGE system allows shooters to seamlessly switch between calibers on the same serialized platform by swapping just three key components: the magazine well, bolt head and barrel. Engineered for an unparalleled shooting experience, the UXR features a unique bore-evacuation chamber within the barrel, paired with a modified long-stroke piston system, resulting in a smoother shooting cycle and significantly reduced recoil. Whether engaging in long-range precision shooting or adapting to fast-paced tactical environments, the UXR provides the ultimate balance of versatility, reliability and cutting-edge performance.

Modified long stroke piston system enhances reliability and reduces fouling for consistent performance
The FRC compensator reduces muzzle rise and recoil for improved shooting stability and accuracy
M-LOK free-float handguard provides superior modularity for accessory mounting and improved heat dissipation
