Leupold QRW Cross-Slot Base Set Winchester 70 Matte Black 180294

The Leupold 180294 QRW Cross-Slot Base Set transforms Winchester Model 70 rifles into precision platforms ready for quick-detach optics mounting. This matte black base system eliminates the limitations of traditional rings while providing rock-solid scope attachment that maintains zero through repeated mounting cycles.

What Makes This Different

The QRW (Quick Release Weaver) system uses cross-slot technology that distributes mounting stress across a broader surface area compared to standard dovetail bases. Each base features precision-machined aluminum construction with a hard-anodized finish that resists wear from repeated scope changes. The cross-slot design accepts Weaver and Picatinny-style rings while providing enhanced grip strength that prevents scope creep under heavy recoil.

Key Features

• Cross-slot design provides superior grip strength and recoil resistance
• Precision-machined 6061-T6 aluminum construction with matte black anodizing
• Compatible with Weaver and Picatinny ring systems
• Designed specifically for Winchester Model 70 receiver dimensions
• Quick-detach capability maintains zero through mounting cycles
• Low-profile design minimizes scope height requirements
• Includes all necessary mounting hardware and thread-locking compound

Field performance demonstrates the base set's ability to maintain point of impact consistency through temperature extremes and sustained firing sessions. The aluminum construction provides thermal stability that prevents scope shift during extended range sessions, while the cross-slot geometry distributes mounting forces to prevent receiver damage. Hunters appreciate the quick-detach capability for scope removal during transport, while competitive shooters rely on the system's return-to-zero reliability.
