Idaho-based Primary Weapon Systems (PWS) has a fairly new and highly modular semi-auto rifle, the PWS UXR. Upon first glance, it’s extremely hard not to think of other designs, such as the original Magpul Masada (better known as the ACR) or even the FN SCAR—this is especially because of the way the PWS UXR’s short-stroke piston-actuated rotating bolt works. Not to mention its multi-role and multi-caliber adaptability.
Switching calibers and barrel lengths is straightforward and keeps the same serialized upper receiver in place. There are only three parts that need to be swapped out in order to effect change: the barrel, magazine well, and bolt head. Naturally, the sizing of these parts depends on the cartridge itself.
From Our Friends At Athlon Outdoors:
The UXR launches initially in .223 Wylde and .300 BLK. But the line, when fully developed, will give shooters the ability to switch between numerous chamberings via caliber conversion kits. Additional chamberings in .308 Win and 8.6 BLK are planned for later this year. But we fully expect anything and everything from 7.62×39 to 6.5 Creedmoor rolled into conversion kits as well, as the platform lends itself to present offerings in everything from door-kicking to PRS cartridges.
The platform utilizes a host of component upgrades, including a folding stock design, adjustable length of pull, and adjustable cheek piece, along with fully ambidextrous controls. Finally, and this may be one of the more impressive aspects of the system, the UXR delivers a return to zero after conversions measures a mere 1/2-minute of angle. That should keep you on target, no matter the caliber, from entry gun out to long-range DMR.
