The Weaver Extended Multi-Slot Base (brand part number 99501) mounts a scope to a Remington 700 long-action rifle while adding an extra inch of forward ring placement over a standard base. Weaver machines it from aircraft-grade 6061-T6 aluminum and finishes it with a Type-III hard coat anodized matte black coating, so it holds zero under recoil and resists wear from field use. The multi-slot layout accepts either Picatinny or Weaver-style rings, giving a shooter flexibility to run whatever mounting hardware they already own. It’s a direct-fit, no-gunsmithing upgrade for a Remington 700 LA owner who wants more ring position options than the factory base allows.
