The Primary Weapons Systems (PWS) UXR Elite 16″ AR rifle is engineered for consistent, reliable performance across demanding shooting disciplines. Chambered in 223 Wylde, this platform ensures optimal compatibility with both 5.56x45mm NATO and .233 Remington ammunition, providing the operator with ammunition flexibility without compromising precision. The 16-inch barrel length is selected for its balanced maneuverability and ballistic efficacy, making it suitable for both close-quarters engagements and intermediate range applications.
Key Features
Piston Operating System
The UXR Elite integrates the renowned PWS long-stroke piston operating system. This design significantly redirects gas away from the bolt carrier group, mitigating carbon fouling within the receiver. This engineering choice directly enhances operational reliability and substantially reduces the maintenance burden characteristic of direct impingement systems, ensuring the rifle maintains function under sustained fire and adverse conditions.
Caliber and Barrel Configuration
The 223 Wylde chambering offers a critical advantage, facilitating safe and accurate deployment of both 5.56x45mm NATO and .233 Remington cartridges. The 16-inch barrel provides a practical balance, optimizing projectile velocity for effective engagement while retaining a compact profile for ease of handling and transport. This configuration supports consistent shot placement across a range of operational environments.
