The Weaver extended multi-slot base (brand part no. 99498) is a one-piece scope base built specifically for the Savage 110 short action with an 8-40 screw pattern, with 20 MOA of elevation built directly into the base for long-range shooters running a scope that needs extra up-adjustment. Machined from aircraft-grade 6061-T6 aluminum and finished with a Type-III hard-coat anodized matte black coating, it’s compatible with both Picatinny and Weaver-style rings. The extended design adds a full extra inch of forward length over a standard base, opening up more ring position options for scopes with larger objective bells or unusual eye relief.
