The Weaver Extended Multi-Slot Base (brand part number 99476) mounts a scope to a Winchester XPR long-action rifle while adding an extra inch of forward ring placement over a standard base. Weaver machines it from 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. Built on a Picatinny-style interface, it accepts standard Picatinny rings for a wide choice of mounting hardware. It’s a direct-fit, no-gunsmithing upgrade for a Winchester XPR LA owner who wants more ring position options than the factory base allows.
