Leupold BackCountry Cross-Slot Rem 700 LA 20 MOA Base - Adaptable 8-40 LU187343

The Leupold BackCountry Cross-Slot 1-pc Base is a precision mounting rail engineered specifically for the Remington 700 Long Action. While traditional steel bases can be unnecessarily heavy and standard aluminum can warp under stress, this system offers a rock-solid, lightweight solution. By utilizing 7075-T6 aluminum, Leupold provides a foundation that maintains its dimensional integrity and keeps your optic perfectly zeroed, even through the heavy recoil cycles of long-action calibers.

The technical edge of this base comes from its superior strength-to-weight ratio and built-in 20 MOA cant. The 7075-T6 aircraft-grade aluminum delivers significantly higher tensile strength than standard alloys, virtually eliminating slot deformation. Because it’s a one-piece rail, it distributes recoil energy evenly across the receiver, reducing localized stress and providing the extra elevation travel needed for long-range precision without compromising your bore alignment.

Machined from 7075-T6 aluminum, this lightweight rail sheds unnecessary ounces while actually reinforcing receiver rigidity. It features a unique 8-40 screw adaptability, allowing it to be easily upsized for custom builds or magnum recoil requirements. The versatile cross-slot interface supports both Picatinny and Weaver-style rings, offering a "set-it-and-forget-it" lockup that preserves your zero in the toughest field conditions.
