Weaver Tactical Extended Multi-Slot Picatinny Base Matte for Winchester XPR Long Action

If you're mounting glass on a Winchester XPR in long action, the Weaver Tactical Extended Multi-Slot Picatinny Base gives you real flexibility where it counts. Built from aircraft-grade 6061-T6 aluminum and finished with a Type III hard coat anodize, this extended base stretches an extra inch forward compared to standard mounts—that means more adjustment room, better scope positioning, and easier access to your rifle's controls. Whether you're setting up a tactical rig or a long-range hunter's rifle, this base handles Weaver and Picatinny rings equally well, so you're not locked into one ring ecosystem.

The engineering here is straightforward and solid. Torx screws prevent accidental loosening during recoil cycles, while an integral lug shoulders the rifle's real stress so nothing shifts under fire. The matte finish lives up to practical expectations—no reflection, no glare, just a durable work surface that stays put through hard use. For shooters serious about Winchester XPR long action builds, this is the kind of foundation that lets everything above it perform without compromise.

Available in standard zero cant if you want your optic axis straight and level, or 20 MOA cant if you're pushing distance and want to dial down wind and bullet drop more efficiently. Either way, you get the same rock-solid aluminum platform and no-nonsense design philosophy that makes Weaver bases reliable across the board.

Frequently Asked Questions

Will this Weaver base work with any scope rings I already have?

Yes. This Picatinny base accepts both Picatinny and Weaver-style rings, so if you're reusing rings from another rifle build, compatibility isn't a concern.

What does the extra inch of forward length actually do for me?

The extended reach gives you more rail real estate to position your scope further forward—useful if you're mounting a large objective lens, want a more forward eye relief setup, or need to keep the scope clear of your rifle's controls.

Is the 20 MOA cant worth it for my Winchester XPR?

If you're a long-range shooter who regularly dials for distance, 20 MOA cant lets you use more of your scope's vertical adjustment for actual shooting rather than zeroing. For typical hunting distances, standard zero cant is sufficient.
