Warne‘s Mountain Tech Rail for the Browning X-Bolt Magnum (brand part no. 764320MOA) is a firearm-specific base machined from 7075-T6 aluminum and finished with a mil-spec hardcoat anodized coating for abrasion and corrosion resistance. Self-centering, tapered T-15 Torx screws with black zinc-coated hardware seat the base squarely on the receiver, and the rail accepts both Picatinny and Weaver-style rings while staying NATO-STANAG compatible. It is built to fit Browning X-Bolt Magnum actions, including 300 PRC, 300 RUM, and .375 H&H, as well as X-Bolt 2 Long and Magnum actions. This version ships with 20 MOA of built-in cant to help long-range shooters dial elevation without running out of adjustment, and like the rest of the Mountain Tech line, it is designed and made in the USA.
