PWS UXR .223 Wyle Rifle 14.5" Pinned Barrel with FRC Comp

PWS UXR .223 Wyle Rifle 14.5" Pinned Barrel with FRC Comp

Introducing the Primary Weapons Systems UXR—a revolutionary modular rifle platform engineered to evolve with you. Inspired by the philosophy “beware the man with only one rifle,” the UXR is not just a firearm—it’s a dynamic, precision-built system designed for adaptability, reliability, and unmatched performance.

At its core is a 14.5" 41V50 steel barrel, known for its superior strength, heat resistance, and longevity. Paired with a modified long-stroke piston system, the UXR delivers smoother recoil, cleaner operation, and enhanced reliability—especially when suppressed. The Barrel Xchange System allows seamless caliber swaps between .223 Wylde, 308 WIN, and 300 BLK, with more options on the horizon.

Crafted from a single piece of 7075-T651 aluminum, the ambidextrous receiver and folding buttstock offer rugged durability and ergonomic flexibility. With a 3-position adjustable gas system, Sub-MOA accuracy guarantee, and a newly designed FRC compensator, the UXR is ready for tactical operations, competitive shooting, or backcountry precision.

The UXR Bore Evacuation System

Uniquely equipped with a cutting-edge bore evacuator system inspired by battle-tested armored vehicles, the UXR ensures a shooting experience like no other. This ingenious system efficiently clears propellant gases and airborne residues from the barrel, not only keeping gases away from the shooter but also making it an ideal choice for suppressor use. The UXR's commitment to safety and functionality shines through, providing users with a modern and adaptable firearm that seamlessly integrates proven technology to deliver optimal performance in various shooting scenarios. Elevate your shooting experience with the UXR Rifle, where innovation and safety converge for a truly exceptional firearm.

What is a Bore Evacuator?

The UXR stands out with its innovative inclusion of a bore evacuator, a feature derived from the technology commonly found in armored fighting vehicles, particularly tanks and self-propelled guns. This bore evacuator serves a crucial role by swiftly clearing the gun barrel of lingering gases and airborne residues after each firing, providing a significant enhancement to both safety and functionality.

In armored vehicles, the bore evacuator creates a pressure differential in the barrel, ensuring that propellant gases and combustion residues exit through the muzzle, preventing any potential hazard to the gun crew when the breech opens for reloading. The UXR's bore evacuator, inspired by this battle-tested concept, is a passive device featuring a ring of drilled holes and a cylindrical pressure reservoir sealed to the barrel's surface via a taper lock.

In the firing process, high-pressure gas propels the projectile forward, and the drilled holes enable propellant gases to flow into the reservoir. As the projectile exits the barrel, the pressure drop triggers the stored gas in the reservoir to flow back, utilizing the venturi effect to efficiently draw gases out of the barrel. This ingenious design, seamlessly integrated into the UXR, ensures the effective removal of gases, significantly reducing the risk of hazards associated with backward gas flow.

Enhancements to the basic concept in some designs include dual sets of holes—one forward and one rearward—equipped with check valves to control gas flow. This sophisticated system aids extraction by creating a partial vacuum behind the shell.
