The Primary Weapons UXR-CK-308-14 UXR Conversion Kit in .308 Winchester delivers a flexible caliber-change solution for the PWS UXR platform. This kit centers around a 14.5" barrel with a threaded muzzle device, precision-machined components, and the PWS XChange system, allowing shooters to swap barrel, bolt, and magwell with confidence and repeatable alignment.

Designed for shooters who want to expand their UXR into .308 Win, this conversion kit is well suited for range work, training, and hunting where a compact, accurate barrel is preferred. The intuitive dot alignment system simplifies installation, while the included bolt and barrel maintain the Sub-MOA accuracy potential the UXR line is known for. It reflects Primary Weapons’ focus on modularity, reliability, and thoughtful engineering.
