If you haven’t studied up on the UXR operation manual, or you are more of a visual learner, check out this clip of how easy the UXR XCHANGE conversion process can be when you want to change the caliber or even the barrel length of your UXR rifle. While calibers that share a common bolt head and magazine will only need a quick barrel swap, the UXR has the ability to step up to larger calibers that require different bolt heads and magazine wells to fully convert.
