Talley Manufacturing Scope Base Features The Talley Manufacturing Scope Base uses a proven machined saddle design with double recoil shoulders that immobilize the rings under heavy recoil helping the rifle hold zero across repeated firing sessions. Built from steel and finished in blue the base is engineered specifically for Winchester Model 70 rifles with .860 inch hole spacing excluding magnum-chambered variants that use different bolt patterns. This direct-thread mounting system creates a solid immovable foundation for the scope rings which matters most when shooting harder-recoiling cartridges. The base ships as a two-piece set matched to the Model 70 s standard bolt spacing. This base is designed to accept only Talley Fixed or QD rings ensuring a fully matched ring-and-base system rather than mixing components from different manufacturers. Talley has built a strong reputation for precision-machined mounting hardware trusted by bolt-action rifle shooters for decades. The straightforward two-bolt installation makes mounting a scope quick and repeatable without requiring special tools. For Winchester Model 70 owners looking for a dependable recoil-resistant scope base this Talley mount is a proven long-lasting upgrade.
