Leupold BackCountry Features The Leupold BackCountry cross-slot base is machined from 7075-T6 aluminum giving it exceptional strength relative to its weight which matters for hunters who count every ounce on a long backcountry pack-in. The cross-slot design accepts both Picatinny and Weaver-style rings giving shooters flexibility to choose the ring height and style that best matches their optic without being locked into one mounting system. Because it is engineered specifically to fit the Browning X-Bolt 2 long action receiver installation is a direct precise fit without requiring drilling or fitting work. This purpose-built fitment means the base indexes perfectly to the receiver s cross-slots so the rings and optic sit exactly where Leupold intended for a repeatable secure zero. Leupold builds every mount to the same rugged standard as the optics they secure and the BackCountry base is made in the USA with a guarantee to hold up to a lifetime of hard use. At just 2.40 ounces and 6.30 inches long the base adds minimal bulk to the rifle while providing a solid foundation for a hunting or long-range scope. For Browning X-Bolt 2 Long Action owners this base offers a dependable purpose-built link between the rifle and optic which Leupold considers one of the most critical components in a hunting rig.
