Leupold BackCountry Cross-Slot Base Ruger American Matte Black

The Leupold BackCountry Cross-Slot Base transforms the Ruger American rifle platform into a precision shooting system with secure optic mounting capabilities. This machined aluminum base replaces factory mounting solutions with a robust foundation engineered for consistent zero retention and enhanced accuracy potential.

What Makes This Different

Unlike standard Weaver-style bases, the BackCountry Cross-Slot system utilizes precision-machined cross-slots that distribute mounting stress across a larger surface area. The 7075-T6 aluminum construction provides 40% greater clamping force than traditional bases while maintaining a lightweight profile. Each base undergoes CNC machining to achieve tolerances within 0.001 inches, ensuring perfect alignment between mounting surfaces.

Key Features

• 7075-T6 aluminum construction with Type III hard coat anodizing for maximum durability
• Cross-slot design distributes mounting stress across wider contact area
• Precision CNC machined to 0.001-inch tolerances for perfect scope alignment
• Matte black finish eliminates glare and resists corrosion in field conditions
• Direct replacement for factory Ruger American bases with no gunsmithing required
• Compatible with Leupold PRW and PRW2 ring systems
• Torx screws included for secure, tamper-resistant installation

Field testing demonstrates the BackCountry base maintains zero through temperature extremes from -40°F to 160°F without thermal expansion issues. The cross-slot interface eliminates the forward-backward movement common with traditional dovetail systems, particularly important for magnum calibers and long-range shooting applications. Hunters and precision shooters report consistent point-of-impact stability even after extended transport and handling.
