Leupold BackCountry Cross-Slot Base - Browning AB3 LA 1-pc LU174684

The Leupold BackCountry Cross-Slot 1-pc Base is a purpose-built mounting rail designed specifically for the Browning AB3 Long Action. Unlike traditional heavy steel or softer 6061 aluminum bases—which can add unnecessary bulk or suffer from material "creep" over time—this system provides a rock-solid, lightweight interface. By utilizing 7075-T6 aluminum, Leupold ensures your optic remains perfectly zeroed, even under the sustained recoil of a long-action rifle.

The real strength of this base lies in its superior power-to-weight ratio. 7075-T6 aircraft-grade aluminum offers significantly higher tensile strength than standard alloys, virtually eliminating the risk of slot deformation or screw fatigue. By using a one-piece architecture, the mounting load is distributed evenly across the entire receiver. This minimizes localized stress points and guarantees that your optic stays perfectly aligned with the bore axis, shot after shot.

Precision-machined from 7075-T6 aluminum, this 1.8 oz rail cuts down on rifle weight without sacrificing an ounce of toughness. The versatile cross-slot interface seamlessly hosts both Picatinny and Weaver-style rings for a "set-it-and-forget-it" lockup. Its continuous, one-piece design doesn't just hold your scope; it actually reinforces receiver rigidity to preserve your zero through the most demanding firing cycles.

Features

• 7075-T6 Aluminum Construction: High tensile strength vs. 6061 reduces deformation under long action recoil.
• One-Piece Rail Design: Continuous receiver contact improves structural rigidity and zero retention.
