Availability: In Stock
The Primary Weapons Systems UXR Magwell Assembly for AR-10 is a modular component designed to work within the UXR XChange system, enabling shooters to swap calibers and magazine types on the same platform. Built for both left and right-handed shooters, this ambidextrous magwell gives you flexibility in how you configure and run your rifle—whether you're hunting, shooting long range, or spending time at the range. The XChange ecosystem approach means you can change barrels, magwells, and bolts to shift between calibers, making a single rifle platform handle multiple roles without requiring an entirely new gun.
Part of Primary Weapons' modular AR-10 system, the UXR Magwell Assembly integrates seamlessly with compatible XChange components. The ambidextrous design accommodates either hand without having to reconfigure controls, and the system's magazine compatibility means you can switch ammunition types and capacity alongside your caliber change. This is practical for serious shooters who want to maximize utility from a single lower receiver and platform.
If modularity and adaptability matter to you—whether for tactical training, hunting different game at different distances, or simply running a more efficient armory—the UXR Magwell Assembly is the foundation of that flexibility. Primary Weapons has designed the XChange system to expand over time with new caliber options and barrel lengths, so your investment grows with your needs.

| Model | UCRW0001-01-1F |
| Platform | AR-10 / UXR XChange System |
| Handedness | Ambidextrous |
| Category | Magwell Assembly |
This magwell assembly is designed specifically for the Primary Weapons UXR XChange system. Compatibility with other AR-10 platforms should be confirmed with PWS or a qualified gunsmith.
The UXR XChange system requires swapping the barrel, magwell, and bolt together to change calibers. The magwell assembly alone is one piece of that modular equation.
Primary Weapons has designed the XChange system to support .223 Wylde, .300 BLK, .308 WIN, and 6.5 Creedmoor, with plans to expand the caliber offerings over time.
Yes—the UXR Magwell Assembly features an ambidextrous design, so you can configure it for either hand without additional modifications.
