The Weaver #20A Gloss Top Mount Base is a fundamental building block for any rifle scope setup. This single base—sold individually, so you'll need a matching rear base to complete your mounting system—is made from lightweight aluminum and designed to accept Weaver-pattern rings. Whether you're mounting optics on a hunting rifle, a precision shooter, or even a shotgun or long-range handgun, the #20A delivers a no-frills platform that's proven itself across decades of field use.
Weaver bases are engineered to fit a broad spectrum of rifle models, both vintage and modern. The gloss finish resists reflection and pairs cleanly with most rifle aesthetics. Because bases are sold individually, you have the flexibility to source a matched pair tailored to your specific rifle model—and Weaver offers one-piece base sets for certain platforms if that's your preference. The lightweight aluminum construction keeps added weight to a minimum without sacrificing the rigid, repeatable mounting surface that precision optics demand.
If you're new to mounting scopes or rebuilding a rifle's optic setup, the key thing to remember is that bases are the foundation of accuracy. A quality base ensures your rings and scope sit true and stay put through recoil and handling. The #20A has been a go-to choice for gunsmithing shops and shooters for good reason—it's straightforward, reliable, and compatible with a vast range of firearms. Pair it with a matching rear base and your choice of Weaver rings to complete the system.

| Brand | Weaver |
| Material | Aluminum |
| Finish | Gloss |
| Ring Pattern | Weaver |
| Quantity | Single base (front or rear) |
The #20A is sold individually. To mount a scope, you'll need both a front and a rear base, so you'll order two—one for each position on your rifle's receiver. Some rifle models qualify for one-piece base sets or pre-paired options; check your specific rifle model for those alternatives.
Weaver bases are engineered to fit a wide range of modern and older rifle models, as well as shotguns and long-range handguns. The right base for your rifle depends on your specific firearm—we recommend confirming your model before ordering to ensure proper fit.
The #20A is designed to accept Weaver-pattern rings. Make sure any rings you choose are marked as Weaver-compatible to ensure they mount securely to this base.
The #20A is constructed from lightweight aluminum, so it adds minimal weight to your rifle setup compared to heavier materials, while maintaining the rigidity needed for precise scope mounting.
