Leupold 171352 BackCountry Cross-Slot Base Weatherby Mark V Matte

The Leupold 171352 BackCountry Cross-Slot Base delivers precision mounting for Weatherby Mark V rifles with advanced cross-slot technology. This matte black base eliminates traditional ring alignment issues while providing rock-solid scope retention under heavy recoil conditions.

What Makes This Different

The BackCountry Cross-Slot system uses machined slots instead of traditional holes, allowing infinite scope positioning along the base length. Standard bases force shooters into fixed ring positions that may not optimize eye relief or scope placement. This cross-slot design accommodates any ring spacing while maintaining consistent clamping force across the entire contact surface.

Key Features

• Cross-slot technology for infinite ring positioning and optimal scope placement
• Precision-machined 7075-T6 aluminum construction for maximum strength-to-weight ratio
• Matte black anodized finish resists corrosion and eliminates glare
• Custom-fitted for Weatherby Mark V action with exact bolt clearance
• Compatible with all major ring manufacturers using cross-slot mounting systems
• Low-profile design maintains clean rifle lines and reduces snag points
• Factory-drilled and tapped mounting holes ensure perfect receiver alignment

Field performance remains consistent across temperature extremes and heavy recoil cartridges. The aluminum construction handles magnum calibers without flexing or shifting under repeated firing cycles. Hunters appreciate the corrosion resistance during extended backcountry expeditions, while competitive shooters rely on the repeatable zero retention between matches.
