If you’re feeling some Robinson XCR, SIG MCX, Bren 2, SCAR, JAKL, or ACR vibes from this, you’re not alone. And maybe not wrong. The PWS UXR (User Xchange Rifle) is a piston-driven, lightweight, modular, multi-caliber long gun from the boys in Boise. 

Primary Weapon Systems says its design allows for “…revolutionary, unparalleled modularity.” It’s too soon to know how accurate that claim is, but PWS has an excellent track record, and the design is damn sure interesting, so maybe it isn’t hyperbole. 

We’ll get our first real look at it during Industry Day at the Range the day before SHOT Show. Meanwhile, we’ll have to rely on what we know from the press release, the product description on their site, and a great video from Guns America (see below). 

PWS UXR

The new Primary Weapons platform will initially be available in 2.23 Wylde and 300 BLK variations, with .308 WIN, 8.6 BLK, and 7.62×39 versions coming in the future. It utilizes a patent-pending design called the Xchange system, which allows a user to transition from caliber to caliber and configuration to configuration. Take note here…the upper receiver is the only serialized part of the weapon. 

Interdasting, eh? 

A number of customization features make the UXR platform’s functionality, ergonomics, comfort, and even aesthetics adaptable. Not to mention making it more likely you can source ammo.

Some of those features include:

  • Interchangeable UXR barrel system
  • Interchangeable magwell to handle different kinds of mags and calibers (STANAG to AK and back, etc.)
  • Interchangeable bolt head 
  • Adjustable buttstock that folds left or right
  • Adjustable cheek plate 
  • Ambidextrous (~able) 45° selector switch and mag release
  • Ambidextrous non-reciprocating charging handle
  • Utilizes AR grips and AR triggers
  • Newly-designed Bore Evacuator
  • Modified long-stroke piston system (3 settings: normal, suppressed, “adverse”)

The PWS UXR is a modular, multi-caliber rifle that uses the Primary Weapon Systerms (PWS) Xchange System.

That gas system will definitely be worth a hard look. If it works the way they say it will, it’ll allow a user to swap calibers and barrels to suit mission and ammo availability without having to adjust the gas system every time. There are several reasons such modularity will be lauded by some, not least the ability to switch from personal protection to longer-distance precision to competitive shooting (et al.) with ease. 

Along those same lines, take now of the Bore Evacuator. It’s intended to reduce back pressure; this has particularly obvious benefits for using a suppressor.

Will they wind up doing whole firearms or conversion kits in 6mm ARC, 6.5 Creedmoor or other calibers? Hopefully, we’ll know soon. They’ve said they intend to drop new caliber options every quarter or so. 

Here’s a look at the launch video. 

 

Guns America did an excellent in-depth look at the PWS UXR; it’s worth your time. Meantime, here’s the overview.

 

It looks like they’re going to run about $2,500 MSRP.
