This guide details the caliber conversion process for the Primary Weapon Systems (PWS) UXR rifle, as demonstrated by PWS presenter Corey. The UXR is designed for rapid caliber changes, allowing users to switch between calibers like 5.56mm, .300 Blackout, and .308 in under 90 seconds by swapping the barrel, bolt head, and magazine well. The process involves using a 5/32 Allen wrench to remove the barrel, changing the bolt head and magazine well, and then re-torquing the barrel to 80 inch-pounds to ensure a sub-half-MOA return to zero.
