Weaver Mounts 99477 Extended Multi-Slot Base Black Anodized Aluminum - Winchester XPR Short Action

The Weaver Mounts 99477 Extended Multi-Slot Base is a one-piece scope mounting platform engineered specifically for the Winchester XPR Short Action rifle. Manufactured from 6061-T6 aircraft-grade aluminum and finished in a matte Type III hard coat anodized black, this base is built to handle hard use in the field while resisting corrosion and wear over years of service.

The extended profile delivers an additional 1 inch of forward length compared to a standard base, giving you extra rail space for flexible optic positioning. The full-length multi-slot top is Picatinny and Weaver ring compatible, accepting both Weaver cross-slot rings and Picatinny rings so you can pair the base with a wide range of modern optics.

The 99477 mounts directly to the Winchester XPR short action receiver for a straightforward installation. Rings are sold separately and should be selected to match your optic's tube diameter and required mounting height. As a one-piece base, it provides a solid, repeatable mounting platform that holds zero through removal and reinstallation, making it a smart upgrade for any Winchester XPR short action rifle.
