Leupold BackCountry Cross-Slot 1-PC Base Features The Leupold BackCountry Cross-Slot Base is machined from 7075-T6 aluminum a material chosen for its strength-to-weight ratio and resistance to the stresses a scope mount sees under recoil. Built specifically for Browning A-Bolt long action rifles it installs as a direct fit one-piece base without requiring any additional machining or fitting work. The 20 MOA of built-in elevation shifts the scope s adjustment range upward which helps long-range shooters avoid running out of internal elevation travel on distant targets. This is particularly useful for magnum and long-range cartridges commonly paired with a long action receiver. The matte black finish reduces glare that could otherwise give away a shooter s position or distract from a clean sight picture in bright conditions. As a one-piece design the base offers a more rigid mounting platform than a two-piece base system which can help maintain zero under repeated recoil. Leupold s reputation for durable field-ready optics hardware extends to this BackCountry base built to handle hard use in the field. It is available for sale at GrabAGun for Browning A-Bolt long action owners looking to mount a long-range capable scope.
