Leupold BackCountry Cross-Slot Base Savage 110 Round Receiver

The Leupold 180955 BackCountry Cross-Slot Base transforms Savage 110 round receiver rifles into precision platforms capable of accepting modern optics with repeatable zero retention. This machined aluminum base replaces factory mounting solutions with a robust cross-slot design that eliminates scope creep under heavy recoil.

What Makes This Different

Unlike standard Weaver-style bases, the BackCountry Cross-Slot system uses perpendicular mounting slots that distribute clamping forces across a wider surface area. This design reduces stress concentrations by 40% compared to traditional ring mounting methods. The cross-slot configuration allows for precise scope positioning adjustments in 0.25-inch increments without removing rings from the base.

Key Features

• Machined 6061-T6 aluminum construction with Type III hard coat anodizing
• Cross-slot design accommodates standard Picatinny and Weaver rings
• Specifically engineered for Savage 110 round receiver action spacing
• Matte black finish reduces glare and resists corrosion
• Steel mounting screws included with thread-locking compound
• 0 MOA cant maintains natural point of aim
• Compatible with scopes up to 56mm objective diameter

Field testing demonstrates consistent zero retention through temperature cycling from -20°F to 120°F. The base maintains structural integrity under magnum cartridge recoil forces exceeding 50 foot-pounds. Hunters report reliable performance in wet conditions due to the anodized surface treatment that sheds moisture and prevents aluminum oxidation.
