Availability: In Stock
The Weaver #90 Top Mount 1-Piece Base is a no-nonsense aluminum mounting solution for hunters and shooters who want a streamlined, durable platform for their scope rings. If you're building a rifle setup or upgrading an existing optic mount, this single-piece base delivers the rigidity and simplicity that serious shooters expect from Weaver's long-standing lineup. The one-piece design eliminates the need to coordinate separate front and rear bases, making installation straightforward and reducing potential alignment issues.
Weaver bases have earned their reputation through decades of service on everything from classic rifles to modern hunting platforms and tactical builds. The #90's gloss finish resists corrosion while maintaining that traditional, professional appearance. Aluminum construction keeps weight low—a critical consideration for field hunters who count every ounce—without sacrificing the rigidity required for consistent scope return to zero.
Before ordering, verify that the #90 is the correct base for your specific rifle model and action type. Weaver's base lineup spans a wide range of firearms, and matching the right number to your gun is essential for proper fit and function. If you're unsure which base fits your rifle, consult Weaver's compatibility chart or reach out to our team for guidance.
This is a base only; you'll need compatible scope rings to complete your mounting system. Whether you're setting up a hunting rifle, a long-range target gun, or a backup defensive build, the #90 delivers the foundation you need.

The #90 is designed for a range of rifle models and action types. Compatibility varies by specific gun, so check Weaver's base selection guide or contact us to confirm the correct base for your rifle before ordering.
This base is one component of a rifle scope mount. You'll also need compatible Weaver scope rings to attach your optic. The base and rings work together to form your complete mounting system.
The #90 is a one-piece base, which means it serves as both the front and rear mount in a single unit. This integrated design simplifies installation and provides a solid platform for your rings and scope.
A one-piece base like the #90 is machined as a single component that spans the entire length of your rifle's receiver. Two-piece sets use separate front and rear bases. One-piece bases generally offer slightly better alignment simplicity, though either approach can deliver excellent results when properly installed.
