Leupold 174436 QRW Cross-Slot Base Set Winchester XPR Matte Black

The Leupold 174436 QRW Cross-Slot Base Set provides Winchester XPR rifle owners with a precision-engineered mounting platform that eliminates the guesswork from scope installation. This two-piece base system delivers repeatable zero retention and maintains consistent point of impact even after scope removal and reinstallation.

What Makes This Different

The QRW (Quick Release Weaver) system stands apart from standard Weaver bases through its integrated quick-detach mechanism and cross-slot design. While traditional bases require tools for scope removal, this system allows shooters to detach optics in seconds using only the built-in levers. The cross-slot configuration provides 40% more surface contact than standard Weaver rails, distributing recoil forces more effectively across the receiver.

Key Features

• Quick-release levers enable tool-free scope removal and installation
• Cross-slot design increases mounting surface area by 40% over standard rails
• Machined from 7075-T6 aluminum with Type III hard anodizing
• Designed specifically for Winchester XPR receiver dimensions
• Matte black finish reduces glare and matches most rifle finishes
• Compatible with all Weaver-style rings and 1-inch tube scopes
• Includes all necessary mounting screws and thread locker

Field testing demonstrates this base system maintains zero through temperature extremes from -20°F to 140°F. The aluminum construction weighs 3.2 ounces while providing the strength to handle magnum caliber recoil forces. Hunters appreciate the quick-detach capability for transport and storage, while competitive shooters rely on the repeatable return-to-zero performance when switching between different scopes.
