Weaver Mounts Top Mount Base Pairs, Model 48482, for Winchester XPR (8-40), Matte Finish

The Weaver Mounts Top Mount Base Pairs (Model 48482) are precision-engineered scope mounts designed specifically for Winchester XPR rifles chambered in 8-40 calibers. If you're setting up a new XPR or swapping optics, these matched front and rear bases eliminate the guesswork of sourcing compatible components — they're made to work together as a system. Built from lightweight aluminum, they deliver the rigidity needed to handle recoil while keeping unnecessary weight off your rifle.

What sets Weaver bases apart is their cross lock design, a locking mechanism that clamps down hard on your rifle's receiver and holds tight through years of field use and practice. Because they're Weaver bases, they accept any Weaver top mount cross lock rings, so you have flexibility in your ring choice and can upgrade or change rings down the road without replacing the bases themselves. That compatibility and standardization is why Weaver remains the go-to for hunters and shooters building reliable scope systems.

The matte finish resists glare and blends with most hunting rifles, and the no-frills design means there's nothing on these bases to snag in brush or catch light at the wrong moment. Whether you're mounting a hunting scope on a Winchester XPR or setting up a precision rifle for distance shooting, these bases provide a rock-solid foundation that won't shift or loosen under recoil.
