Leupold BackCountry Cross-Slot Base Winchester XPR 20 MOA Matte

The Leupold BackCountry Cross-Slot Base transforms Winchester XPR rifles into precision long-range platforms with its integrated 20 MOA cant. This machined aluminum base extends effective shooting range by compensating for bullet drop at extended distances. Built to Leupold's exacting standards, it provides the rock-solid foundation serious shooters demand for consistent accuracy.

What Makes This Different

Unlike standard zero-cant bases, this BackCountry model incorporates a 20 MOA forward slope that maximizes scope adjustment range. The cross-slot design accepts both Weaver-style and Picatinny rings, offering greater mounting flexibility than proprietary systems. Precision-machined from aircraft-grade aluminum, it maintains zero under heavy recoil and temperature extremes that cause inferior bases to shift.

Key Features

• 20 MOA built-in cant extends long-range shooting capability
• Cross-slot design compatible with Weaver and Picatinny ring systems
• Machined from 6061-T6 aircraft aluminum for maximum strength
• Matte black hard-anodized finish resists corrosion and glare
• Precision-engineered specifically for Winchester XPR action
• Low-profile design maintains rifle balance and handling
• Includes mounting hardware and installation instructions

Field performance centers on the base's ability to maintain scope zero through thousands of rounds and harsh conditions. The 20 MOA cant proves invaluable for hunters pursuing game beyond 400 yards and competitive shooters engaging targets at extended ranges. Weather-sealed construction handles moisture, temperature swings, and UV exposure without degradation. The cross-slot configuration accommodates rings from multiple manufacturers, simplifying scope selection and replacement.
