PWS UXR Elite Rifle 300 Blackout 14.5" Barrel - Piston Driven AR

The PWS UXR Elite rifle delivers superior reliability through its long-stroke piston system, eliminating the gas fouling issues common in direct impingement AR platforms. This 300 Blackout configuration excels in both subsonic and supersonic applications, making it exceptionally versatile for tactical and hunting scenarios.

What Makes This Different

The long-stroke piston operating system runs significantly cleaner than traditional gas impingement designs, reducing maintenance requirements by up to 70%. The modular rail system provides unlimited mounting options while maintaining zero retention through repeated installations. PWS engineering focuses on operational reliability in adverse conditions where standard AR platforms typically struggle.

Key Features

• Long-stroke piston system eliminates gas fouling in the bolt carrier group
• 14.5-inch barrel optimized for 300 Blackout ballistics and maneuverability
• Modular rail interface accepts M-LOK accessories and standard Picatinny mounts
• Enhanced bolt carrier group with tool steel construction
• Ambidextrous controls including safety selector and magazine release
• Adjustable gas block allows tuning for suppressed and unsuppressed firing
• Proprietary muzzle device reduces flash signature and recoil impulse

Field performance demonstrates consistent cycling across temperature extremes from -20°F to 140°F without lubrication adjustments. The 300 Blackout chambering provides effective terminal performance out to 300 yards with supersonic loads while maintaining hearing-safe operation with subsonic ammunition and suppression. Competition shooters report sub-MOA accuracy with quality ammunition, while tactical users appreciate the reduced maintenance schedule during high-round-count training.
