Leupold BackCountry Cross-Slot Base Features The Leupold BackCountry Cross-Slot Base is machined from 7075-T6 aluminum a material chosen for its strength-to-weight ratio making this one of the lightest and most rugged mounting bases available for a long action rifle. Its cross-slot design accepts both Picatinny and Weaver style rings giving shooters flexibility in choosing the ring system that best matches their existing optics setup. Built-in 20 MOA of elevation helps extend a rifle s effective long-range capability by compensating for bullet drop at distance reducing how much elevation adjustment the scope s own turrets need to provide. This design consideration is especially valuable for hunters and shooters engaging targets well beyond typical hunting ranges. At 6.3 inches long and just 0.25 inches tall the base adds minimal bulk to a rifle s profile while still providing a secure mounting platform. Weighing only 1.85 ounces it contributes negligible added weight to a hunting rifle carried over long distances in the field. Finished in Black the base blends cleanly with most rifle finishes without drawing unwanted attention. Long action rifle owners looking for a lightweight versatile scope base with built-in elevation will find the BackCountry Cross-Slot Base a strong choice.
