The Weaver 48420 Top Mount Base transforms your Savage 110 rifle into a precision optics platform with rock-solid mounting capability. This machined aluminum base accepts standard Weaver-style rings while maintaining the low profile essential for proper scope alignment and cheek weld consistency.
What Makes This Different
Unlike flimsy stamped bases, the Weaver 48420 features CNC-machined construction from aircraft-grade aluminum with precision-cut crossslots that eliminate ring slippage under heavy recoil. The matte black anodized finish resists corrosion and eliminates glare, while the exact fitment to Savage 110 receiver dimensions ensures perfect alignment without shimming or gunsmithing modifications.
Key Features
- CNC-machined 6061-T6 aluminum construction for maximum strength-to-weight ratio
- Standard Weaver crossslot pattern accepts all Weaver and Picatinny-compatible rings
- Includes hardened 8-40 mounting screws specifically sized for Savage 110 receivers
- Matte black Type III hard anodizing prevents corrosion and scope reflection
- Low-profile design maintains proper scope height for comfortable shooting position
- Precision-machined receiver contact surfaces ensure perfect fit without bedding
- Compatible with all Savage 110 variants including AccuTrigger models
Field testing demonstrates the base's ability to maintain zero through thousands of rounds across multiple calibers from .243 Winchester to .300 Winchester Magnum. The rigid aluminum construction transfers recoil forces directly to the receiver without flexing, while the corrosion-resistant finish withstands harsh hunting conditions from desert heat to mountain snow. Competition shooters rely on this base for consistent point-of-impact reliability during rapid-fire stages.
