Leupold 49866 QRW Cross-Slot Base Set Remington 541 Black Gloss

The Leupold 49866 QRW Cross-Slot Base Set delivers precision mounting for Remington 541 rifles with quick-release functionality that maintains zero shot after shot. This two-piece base system transforms scope mounting from a permanent installation into a field-adaptable system. Machined from aircraft-grade aluminum with a black gloss finish, these bases provide the rock-solid foundation serious shooters demand.

What Makes This Different

Unlike standard Weaver-style bases, the QRW (Quick Release Weaver) system incorporates cross-slots that lock rings in place while allowing rapid scope removal and reattachment. The precision-machined surfaces ensure consistent scope positioning within 0.1 MOA of original zero when properly torqued. Each base undergoes CNC machining to tolerances measured in thousandths of an inch, eliminating the play and inconsistency found in cast alternatives.

Key Features

• Quick-release cross-slot design maintains zero through repeated scope mounting cycles
• Two-piece aluminum construction specifically engineered for Remington 541 receiver dimensions
• Black gloss anodized finish resists corrosion and provides professional appearance
• Standard Weaver/Picatinny ring compatibility accommodates most scope ring brands
• Precision CNC machining ensures consistent 0.005-inch tolerances
• Torx screws included with thread-locking compound pre-applied
• Low-profile design maintains clean rifle lines while maximizing scope adjustment range

Field testing confirms these bases maintain point of impact through temperature extremes from -20°F to 140°F. Competition shooters appreciate the ability to switch between different scopes for varying match requirements without losing established zeros. The cross-slot engagement prevents scope creep under heavy recoil, making this system suitable for precision rimfire competition and small game hunting applications.
