Leupold 171349 BackCountry Cross-Slot Base Tikka T3/T3x 20 MOA

The Leupold 171349 BackCountry Cross-Slot Base delivers precision scope mounting for Tikka T3 and T3x rifles with built-in 20 MOA cant for extended long-range capability. This machined aluminum base transforms standard rifles into precision platforms capable of engaging targets beyond 600 yards.

What Makes This Different

Unlike standard flat bases, this BackCountry base incorporates 20 minutes of angle built into the design, effectively extending usable scope adjustment range by 5.8 inches at 100 yards. The cross-slot design accepts both Picatinny and Weaver-style rings while maintaining zero repeatability through multiple scope changes. CNC machining from 6061-T6 aluminum ensures dimensional consistency within 0.001 inches.

Key Features

• 20 MOA built-in cant extends long-range capability beyond 800 yards
• Cross-slot design accommodates Picatinny and Weaver ring systems
• CNC machined from 6061-T6 aluminum for strength and precision
• Matte black hard anodized finish resists corrosion and glare
• Direct bolt-on installation for Tikka T3 and T3x action patterns
• Windage adjustment capability through slotted mounting holes
• Low-profile design maintains rifle balance and handling characteristics

Field testing demonstrates consistent zero retention through temperature extremes from -20°F to 140°F. The 20 MOA cant proves particularly valuable for competitive long-range shooting and precision hunting applications where maximum scope adjustment becomes critical. Hard anodized finish withstands thousands of rounds without showing wear or losing dimensional stability.
