The Weaver 48336 Multi-Slot Base transforms the Remington 597 rimfire rifle into a precision optics platform. This machined aluminum base replaces the factory grooved receiver with a robust Weaver-style rail system that accepts standard rings and mounts. Built specifically for the 597's unique receiver dimensions, it provides a rock-solid foundation for scopes, red dots, and other optical accessories.
What Makes This Different
Unlike generic aftermarket bases that require modification or shimming, the 48336 features precision-machined mounting points that align perfectly with the Remington 597's factory holes. The multi-slot design offers 4.5 inches of mounting surface with cross-slots spaced at standard intervals. This extended length accommodates longer scopes and allows optimal eye relief positioning for shooters of different sizes.
Key Features
- Precision-machined 6061-T6 aluminum construction for maximum strength-to-weight ratio
- Matte black anodized finish resists corrosion and reduces glare
- Direct bolt-on installation using factory mounting holes - no gunsmithing required
- Standard Weaver cross-slots accept all compatible rings and mounts
- 4.5-inch mounting surface provides flexibility for scope positioning
- Low-profile design maintains clean sight lines and rifle balance
- Compatible with Remington 597 in all calibers (.22 LR, .22 WMR, .17 HMR)
Field testing demonstrates the base maintains zero through thousands of rounds and temperature extremes. The rigid aluminum construction eliminates the flex common in factory polymer receivers under scope mounting stress. Hunters appreciate the consistent point of impact when switching between iron sights and optics, while competitive shooters benefit from the repeatable scope mounting for equipment changes between matches.
