The Primary Weapons Systems UXR Elite conversion kit in .308 Win with a 16-inch barrel gives you a practical path to multi-caliber shooting without buying a second rifle. Built on PWS's XChange system, this kit lets you swap barrel, bolt, and magwell to shift your rifle between calibers—no gunsmith, no guesswork. If you're a rifleman who wants the flexibility to run different cartridges on one platform, or you're looking to expand an existing UXR build, this is a straightforward way to do it.
What makes the XChange system stand out is its simplicity. PWS engineered a dot-matching interface so you pair up corresponding marks on each component; it's intuitive enough that swaps happen quickly and repeatably. You get a 16-inch barrel—a practical middle ground for velocity and handling—and all the hardware needed to complete the conversion on your UXR lower. The barrel is Boise-made and held to sub-MOA accuracy standards with quality ammunition, so you're not sacrificing precision for modularity.
This kit is built for shooters who value adaptability. Whether you're zeroing in a new cartridge for hunting season, testing loads at the range, or simply want the option to reconfigure without a major investment, the UXR platform delivers that flexibility at a price that doesn't demand a second mortgage. PWS backs every product with their warranty, covering defects and issues so you can trust your gear in the field or on the bench.
