The Primary Weapons Systems UXR Elite .300 AAC Blackout 14.5″ is a modular short-barrel rifle built for families who want one platform that adapts to different shooting needs. Chambered in .300 AAC Blackout with a 14.5-inch barrel, it uses PWS’s Barrel Xchange System to swap calibers and barrel lengths in minutes. The modified long-stroke piston system runs clean and reliable, while the three-position adjustable gas block includes a dedicated suppressor setting.

Key Features
- Barrel Xchange System — WHY IT MATTERS: You can switch between .300 Blackout and other calibers without tools, so one rifle does duty for home defense, hunting, and plinking. Perfect for families sharing a single platform.
- Modified Long Stroke Piston — WHY IT MATTERS: Keeps carbon and fouling out of the receiver, which means less cleaning and more time shooting. It runs cleaner than direct impingement systems, especially important for newer shooters.
- Three-Position Adjustable Gas Block with Suppressor Setting — WHY IT MATTERS: You can dial the gas for suppressed or unsuppressed fire, reducing recoil and noise. This makes the rifle more comfortable for youth shooters and beginners.
- Ambidextrous Controls and Folding Adjustable Stock — WHY IT MATTERS: Left-handed or right-handed shooters can operate the safety, bolt release, and magazine release without changing grip. The folding stock makes storage and transport easier for range trips.
Who It’s For
This rifle is built for families teaching the next generation to shoot. The .300 AAC Blackout round is softer recoiling than 5.56 NATO, so it’s easier on young shoulders. The modular design lets you change barrel lengths for different seasons—short for home defense, longer for deer hunting. If you’re a parent who wants one rifle that grows with your teenager’s skills, the UXR Elite fits that role.
Pros and Cons
Pros: Quick caliber changes, clean piston operation, suppressor-ready, ambidextrous for all shooters, adjustable stock for growing kids.
Cons: The pinned and welded compensator means you cannot easily swap muzzle devices without a gunsmith. Also, at $2499.95, it’s a premium investment for a family’s first rifle.
