The Weaver #411 Top Mount Base is a single-piece aluminum scope mounting solution built to anchor your optics securely without gunsmithing. If you're mounting a rifle scope and want a no-fuss, direct-to-receiver base that plays well with Weaver-compatible rings, this gloss black base delivers the straightforward functionality that field-proven mounting systems are known for. One-piece design means less to go wrong and easier alignment than a two-piece setup.
Weaver has spent decades refining mount geometry, and this top mount base reflects that heritage—it's engineered to position your scope at a height and angle that works across different rifle platforms. The gloss black finish resists glare and blends with modern tactical rifles and traditional hunting guns alike. Installation is straightforward: the base comes with custom screws sized for a secure, permanent fit to your receiver, with no drilling or tapping required on your part.
Whether you're building a precision rifle for the range, setting up a hunting gun, or upgrading an existing optics system, a quality base is where accuracy starts. The #411 is a time-tested choice that hunters and shooters reach for because it works, stays put, and keeps your scope exactly where you aimed it.
