PWS UXR Conversion Kit .223 Wylde 16″ Barrel

Description

The Primary Weapons Systems UXR Conversion Kit in .223 Wylde with a 16″ barrel provides the components required to change calibers on the UXR serialized platform by exchanging the barrel, bolt head, and magazine well. The kit is finished in black and uses PWS’s XChange dot system to help ensure correct alignment during component changes. The barrel design incorporates a bore-evacuation chamber and the platform uses a modified long-stroke piston system, both intended to influence shot dynamics and recoil characteristics.
