The Weaver #70 Top Mount 1 Piece Base is a solid, no-nonsense mounting solution for hunters and shooters who want a simple, reliable way to attach a scope to their rifle. Built from lightweight aluminum, this single-piece base keeps things straightforward—one base does the job of securing your optic without the complexity of a two-piece system. Whether you're setting up a hunting rifle, a long-range competition gun, or even a shotgun or handgun with optics, the #70 delivers the kind of dependable performance that's made Weaver a go-to name in the shooting sports for decades.
A one-piece base eliminates the potential for front-to-rear misalignment that can plague two-piece setups, giving you confidence that your zero will hold shot after shot. The gloss finish resists corrosion while maintaining a clean, professional look. Since Weaver bases are engineered to work across a wide range of rifle models—both modern and older platforms—you're getting versatility without sacrificing precision. This is the kind of equipment that works when you need it to, whether you're out in the field or punching paper at the range.
Installation is straightforward for anyone comfortable with basic gunsmithing or comfortable handing it off to a gunsmith. Just make sure you've got the correct base for your specific rifle model; Weaver offers multiple base options across their lineup, so double-check the fit before you order. If you're building a scope-ready setup or upgrading an existing one, the #70 is a time-tested choice that won't let you down.

| Material | Aluminum |
| Finish | Gloss |
| Configuration | Single Piece |
The #70 is designed for a wide range of rifle models, both modern and older shotguns and long-range handguns. However, compatibility is specific to your exact firearm. Check the Weaver base selector or contact customer service with your rifle's make and model to confirm the #70 is correct for your gun.
The Weaver #70 is a one-piece base, meaning a single mounting unit secures your scope. A one-piece design eliminates the risk of misalignment between separate front and rear bases, which can occur with two-piece systems.
The base itself is the foundation; you'll also need a scope and appropriate rings that match your base's top surface to complete the setup. Make sure your rings and scope are compatible with Weaver-style bases before purchasing.
