Talley Winchester Model 70 Long Action Picatinny Base, 20 MOA

The Talley Winchester Model 70 Long Action Picatinny Base with 20 MOA of built-in elevation (Talley part no. PLM252702) is a direct-fit base for the Winchester Model 70 standard and short-magnum long actions. Machined steel construction bolts to the factory receiver holes with no drilling or gunsmithing, and the Picatinny rail interface accepts any standard cross-slot ring or mount rather than proprietary Talley rings alone. The built-in 20 MOA of elevation is aimed at long-range shooters who need to bank extra elevation adjustment into the base itself, extending a scope’s usable dial range well past what a flat base allows.
