Winchester 1-Piece Weaver Style Base Winchester SX4, SX3, SX2 Matte Black

A Winchester 1-piece Weaver style base gives your SX4, SX3, or SX2 shotgun a solid platform for mounting a scope. Unlike two-piece bases, a single-piece design eliminates flex between the receiver and rail, which matters when you're counting on repeatable accuracy from a shotgun. This matte black base accepts standard Weaver-format scope rings, giving you real flexibility in ring placement and scope positioning—critical when working with shotgun ergonomics and sight picture. The machined alloy construction keeps weight minimal without sacrificing the rigidity that precision shooting demands.

Winchester shotgun hunters and 3-gun competitors know that mounting optics on a shotgun is different from rifles. You need a base that won't shift, and one that lets you dial in the right eye relief and height. The Weaver format is the industry standard, so you're not locked into Winchester rings or limited options down the road. Whether you're running a red dot for tactical drills, a slug scope for deer hunting, or a low-power variable for clay sports, this base gives you the anchor point to make it work.

Installation is straightforward for anyone comfortable with basic gunsmithing. The machined fit is precise, and the matte finish blends with the shotgun's receiver without adding shine that catches light. This is a dependable piece of Winchester hardware—nothing fancy, just solid engineering that does its job and stays put.
