The Weaver #55 Top Mount Base is a lightweight aluminum mounting base designed to anchor quality optics on rifles, shotguns, and long-range handguns. Built in a classic gloss finish, this base delivers the simplicity and reliability that serious shooters have trusted for generations. Whether you're mounting a scope on a precision rifle, shotgun, or a handgun rig, the #55 provides a solid foundation for your glass—and it's sold individually, so you'll need to order both front and rear bases to complete your setup.

This base fits a broad range of rifle models, from vintage classics to modern platforms, making it a go-to choice when you need a dependable optic mount without the hassle of proprietary systems. The lightweight aluminum construction keeps your rifle balanced and quick to handle, while the proven Weaver dovetail design has earned its place in countless rigs across the hunting and shooting community. The gloss finish strikes a practical middle ground between aesthetics and durability in the field.

Because optic mounting isn't one-size-fits-all, Weaver offers the #55 alongside a range of other base models to fit specific rifle actions and receiver styles. If you're not certain which base matches your rifle, Weaver's cross-reference will point you to the right number—check the manufacturer's compatibility guide or contact us if you need help identifying the correct base for your gun.
