The Weaver #413 is a top-mounted, one-piece rifle scope base designed for shooters who want a solid, unified platform for mounting optics. Unlike two-piece bases that rely on separate rings, this single aluminum casting provides a rigid foundation that minimizes flex and potential point-of-impact shifts—critical when you're dialing in for hunting, tactical work, or precision shooting. The matte finish resists glare and blends with most rifle aesthetics.
One-piece bases like the #413 excel when you need maximum rigidity without compromise. Because the mount spans the entire receiver as a single unit rather than being split across two separate components, there's no differential settling between front and rear that can plague two-piece designs. Weaver engineered this base to start low on your receiver, giving you options for scope height and eye relief that work with both standard and precision rifle setups.
Installation is straightforward: the base mounts with Weaver's included custom screws, which are designed to hold securely in the specific recoil pad pattern for this model. If you're upgrading an existing Weaver-compatible rifle or building a scope package from scratch, verify your rifle's receiver is compatible with the #413 before ordering—Weaver makes model-specific bases for different firearm platforms.

The #413 is a model-specific base. Verify your rifle's receiver matches the #413 designation before purchase—Weaver manufactures different bases for different firearm platforms. Check your rifle's manual or contact us with your make and model for confirmation.
A one-piece base provides superior rigidity because it's a single aluminum casting that spans your receiver without separate components. This eliminates potential flex between front and rear sections, maintaining zero stability through recoil and temperature changes—especially important for hunting and long-range shooting.
The Weaver #413 comes with custom-fitted mounting screws designed for secure attachment to your specific rifle model.
Yes. The precision engineering and custom screws allow you to remove and reinstall the base, though best practice is to mark screw positions before removal to aid in realignment.
