The Weaver Multi-Slot Extended Base for the Savage 110 long action, 8-40 screw pattern (brand part number 99497) builds in 20 MOA of elevation to help long-range shooters dial in more come-up before running out of scope adjustment. The multi-slot design is compatible with both Picatinny and Weaver-style rings, and the base adds a full inch of forward length over a standard base for more ring placement options when balancing a long-range setup. Weaver machines the base from aircraft-grade 6061-T6 aluminum and finishes it in a matte, Type III hard coat anodize for durability.
