The Talley Manufacturing Winchester Model 70 Picatinny base is a precision scope mounting platform engineered for Winchester Model 70 rifles in both standard long action and short magnum configurations. Built from aluminum and finished in black, this single base gives you the flexibility to position your scope exactly where you want it along the rifle's receiver thanks to multiple mounting slots. The 20 MOA angle is pre-built into the base, making it ideal for long-range hunting and shooting applications where you need additional elevation adjustment range without cranking your scope's turrets to their limits.
Talley bases are known for solid, repeatable performance in the field. This platform accepts Picatinny-spec rings as well as most Weaver-style rings, so you're not locked into a single ring ecosystem. That compatibility matters when you're building or rebuilding a rifle and want to use quality rings you already have on hand. The aluminum construction keeps weight minimal while maintaining the rigidity required for accurate scope mounting on a centerfire rifle.
Whether you're setting up a classic Winchester 70 for long-range hunting or precision shooting at distance, this base gives you the adjustment range and mounting flexibility to dial in your optic exactly right. The 20 MOA angle means you start your elevation adjustments from a position that favors longer distances, reducing the chance you'll run out of up-elevation on your scope when stretching beyond 500 yards.

A 20 MOA angle is built into the base to extend your scope's elevation adjustment range for long-range hunting and precision shooting. This allows you to dial your scope's turrets in a more efficient range when shooting at extended distances, rather than maxing out the scope's internal elevation adjustment.
