Weaver Mounts 99476 Extended Multi-Slot Base Black Anodized Aluminum - Winchester XPR Long Action

The Weaver Mounts 99476 Extended Multi-Slot Base is a precision-machined, one-piece Picatinny scope base purpose-built for the Winchester XPR Long Action rifle. Designed to mount directly to the rifle's receiver, this base delivers a clean, optics-ready platform for hunters and shooters looking to pair their XPR Long Action with a modern optic.

The extended profile provides an additional 1 inch of forward length over the standard base, giving users greater mounting flexibility for longer scopes, night-vision devices, and accessories that benefit from extra rail real estate. The multi-slot design accepts both Picatinny and Weaver-style rings, making it a versatile choice for a wide range of optic footprints.

Machined from 6061-T6 aircraft-grade aluminum and finished in a matte Type-III hard coat anodized black, the 99476 is built to handle the recoil and field conditions of long-action hunting use. The hard-anodized surface resists scratches, corrosion, and the wear that comes with repeated ring mounting. This listing is for the base only; rings are sold separately.
