Weaver #40A Extended Top Mount Base, Gloss Finish$8.49
Availability: In Stock
The Weaver #40A Extended Top Mount Base is a straightforward, reliable scope mounting solution for hunters and shooters who need to secure optics on rifles, shotguns, or long-range handguns. This matte-finish aluminum base is engineered to fit a broad range of modern and classic rifle models, making it a practical choice whether you're building out a new setup or upgrading legacy firearms. The extended design provides the additional elevation adjustment range some shooters need, particularly those working with longer sight-line distances or specialized shooting applications.
Weaver bases have been a standard in the industry for decades, and the #40A carries that reputation for straightforward functionality. The matte finish resists glare and blends cleanly with most rifle finishes. Because bases work best as a matched pair—one front, one rear—most setups will require ordering two units. Weaver offers this base individually so you can select the exact combination your firearm needs, or look for pre-paired sets if available for your specific rifle model.
Installation and alignment are straightforward if you follow your rifle manufacturer's torque specs and use a quality level. The aluminum construction keeps weight minimal, which matters on rifles where every ounce counts. Whether you're mounting a hunting scope, a tactical optic, or a long-range target sight, the #40A is built to stay put without fuss.

Scope mounting requires both a front and rear base. The #40A is sold individually, so you'll typically order two—one for the front ring and one for the rear. Weaver does offer pre-paired base sets for some rifle models if you want a matched pair; check compatibility for your specific firearm.
The #40A is designed to fit a wide range of modern and older rifle models, as well as shotguns and long-range handguns. Weaver publishes a compatibility chart to help you confirm the right base for your firearm. When in doubt, verify your rifle or shotgun model against that reference before ordering.
The extended design provides additional elevation adjustment range compared to standard bases, which is useful for longer-distance shooting or when you need extra vertical adjustment to zero your optic properly.
The matte finish serves a practical purpose: it reduces glare and light reflection that could otherwise catch your eye or create glint that gives away your position. It also blends well with most rifle finishes for a clean, unified appearance.
