Weaver

The Weaver #13 Top Mount Base is a straightforward aluminum scope mounting solution built for rifles that need a reliable, no-fuss way to attach optics. These bases are engineered to work across a broad spectrum of modern and vintage rifle designs, as well as shotguns and long-range handguns—making them a practical choice for hunters and shooters who own multiple firearms or who want compatibility flexibility. Sold individually, you'll need to order both a front and rear base to complete your mounting setup, though some rifle models may qualify for matched base pair sets that arrive pre-paired and ready to go.
Weaver bases have earned their reputation through decades of straightforward functionality. The #13 fits into that legacy: lightweight aluminum construction keeps extra weight off your rifle, and the gloss finish resists rust and corrosion in the field. If you're working with a rifle platform that doesn't lend itself to picatinny rails or integrated mounting systems, a Weaver top mount base is often the quickest path to getting glass on your gun without aftermarket gunsmithing.
Because Weaver makes bases for a broad range of rifle models and actions, confirming which base matches your specific firearm is the critical step before ordering. The #13 designation is rifle-specific, so double-check that it's the correct fit for your action type before committing. Once mounted, these bases provide a solid platform for scope rings or integrated scope mounts, and they'll hold zero through normal hunting and range use.

| Finish | Gloss |
| Material | Aluminum |

The #13 is designed for a range of rifle models and actions, as well as compatible shotguns and long-range handguns. Because base fitment is specific to your firearm's action and receiver type, confirm your exact rifle model before ordering to ensure compatibility.
You'll need both a front and rear base to complete a scope mounting system. They are sold individually, though some rifle models qualify for matched base pair sets that come together. Check whether your rifle qualifies for a pre-paired set option.
