Leupold 171348 BackCountry Cross-Slot Base Tikka T3/T3X Matte Black

The Leupold 171348 BackCountry Cross-Slot Base transforms Tikka T3 and T3X rifles into precision platforms ready for serious optics mounting. This machined aluminum base eliminates the need for traditional rings while providing a rock-solid foundation for scopes in challenging field conditions. Built to Leupold's exacting standards, it delivers the reliability hunters and precision shooters demand when accuracy matters most.

What Makes This Different

Unlike standard Weaver or Picatinny bases, the BackCountry Cross-Slot system integrates directly with compatible Leupold scope rings for enhanced rigidity and reduced point of impact shift. The cross-slot design distributes mounting stress across a wider surface area compared to traditional ring systems. This results in more consistent zero retention through temperature changes and heavy recoil, with mounting surfaces machined to tolerances within 0.001 inches.

Key Features

• Machined 6061-T6 aluminum construction for maximum strength-to-weight ratio
• Cross-slot design eliminates ring slippage and scope movement under recoil
• Matte black anodized finish resists corrosion and reduces glare
• Direct bolt-on installation to Tikka T3 and T3X receiver without gunsmithing
• Compatible with Leupold BackCountry and PRW2 ring systems
• Precision-machined mounting surfaces ensure proper scope alignment
• Low-profile design maintains clean rifle lines and reduces snag points

Field performance centers on maintaining zero through extended shooting sessions and harsh environmental conditions. The rigid aluminum construction handles magnum cartridge recoil without flex, while the anodized finish withstands moisture, salt air, and temperature extremes from arctic hunts to desert competitions. Multiple mounting points distribute stress evenly, preventing the scope creep common with standard ring systems during rapid-fire sequences or extended precision shooting.
