The Weaver #43 top mount rifle scope base is a straightforward, no-nonsense mounting solution for hunters and shooters who want a proven way to get glass on their rifle. Built from lightweight aluminum, this single base handles the job without adding unnecessary weight to your setup. Whether you're mounting a scope on a modern tactical rifle, a classic hunting gun, or even a long-range handgun platform, the #43 is engineered to deliver a solid, repeatable mounting surface that won't complicate your build.
Top mount bases like the #43 fit a wide range of rifle models across different eras and manufacturers—modern production guns, older sporters, and shotguns all benefit from this versatile design. Because it's sold individually, you'll need to order both a front and rear base to complete your scope mounting system. This two-base setup is the industry standard and gives you the flexibility to choose bases that work precisely with your specific rifle model and preferred scope height.
If you're shopping for rifle scope bases, the key is matching the base number to your exact gun. Weaver offers numerous models in their lineup (the #43 is one of many, with options ranging from the #68 through #604), so take a moment to confirm your rifle's compatible base before ordering. The gloss finish adds a classic look while the aluminum construction keeps overall rifle weight down—practical details that matter whether you're hunting in the field or spending time at the range.
You'll need to order two bases—one for the front ring and one for the rear—to properly mount a scope using the top mount system. The #43 is sold individually, so add both a front and rear base to your order.
The #43 is compatible with a wide range of modern and older rifle models, as well as shotguns and long-range handgun platforms. We recommend checking your specific gun's model to confirm the #43 is the correct base, as Weaver offers many different numbers in their lineup.
The #43 is sold as an individual base. Some Weaver models are offered as complete base pair sets, but the #43 is purchased separately for front and rear mounting positions.
