The Weaver #429 Top Mount 1-Piece Base Matte Finish is a solid aluminum scope mount designed to get your optic mounted securely and reliably on your rifle. Built as a single-piece platform with a matte finish, this Weaver base offers the rigidity and precision you need for consistent accuracy—whether you're hunting, running a precision rifle at the range, or building a truck gun for backcountry work. The one-piece design eliminates the alignment issues that can creep in with two-piece setups, giving you a unified mounting surface from the start.

Weaver bases have earned their reputation for no-nonsense dependability over decades of use in the field. The #429 mounts to the top of your receiver and features the standardized Weaver dovetail slots, so it's compatible with any quality scope ring that fits Weaver bases. The matte finish resists glare and blends with most rifle profiles—no shiny reflections to catch an animal's eye or your own scope's glint at distance. The base comes with its own custom-made hardened fastening screws, so you've got everything you need to get started.

Installation is straightforward: drill and tap your receiver (or use existing holes if your rifle is already drilled for Weaver), align the base, and lock it down with the included screws. Removal is just as simple if you ever need to swap it out or service the gun. This is honest, utilitarian engineering—no frills, just a rock-solid foundation for whatever optic system you choose to run on top.
