Talley Steel Base for Winchester 70 (SA) (21.8 mm)

• Steel construction: The all-steel build gives this Talley base the rigidity and wear resistance needed for a dependable scope-to-action interface, especially on hard-used hunting rifles.
• Double recoil shoulder design: Talley’s base geometry helps the mount stay planted under recoil, reducing the chance of movement that can affect zero retention over time.
• Model-specific fit: Designed for Winchester Model 70 short-action patterns with 21.8 mm front spacing, this base is made to match the receiver correctly for a more secure installation.
• 0 MOA profile: The flat base keeps the optic in a neutral mounting position, which suits general hunting and sporting setups where added cant is not required.
• Made in USA: Machined in the United States, this base reflects Talley’s focus on firearm-specific mounting hardware with consistent fit and straightforward field use.

About the Talley Bases Series

Talley Bases are the company’s traditional scope-mount foundation for shooters who want a separate base-and-ring system rather than an integrated one-piece mount. The series covers a wide range of firearm models, and Talley builds each base around a model-specific fit so the mounting surface matches the action it is intended for. That matters in practice because correct fit is the starting point for stable ring alignment and repeatable zero.

Within Talley’s lineup, these bases sit as a classic option for hunters and rifle owners who prefer to pair the base with Talley Fixed Rings or Talley Quick-Detachable Rings. Talley describes the bases as being machined from solid bar stock, and the design uses double recoil shoulders to keep the assembly secure under recoil. The result is a straightforward mounting system with a conventional layout, solid mechanical support, and compatibility across many common sporting rifle actions. For shooters building a practical hunting rifle or replacing worn factory mounting hardware, the Talley Bases series focuses on fit, strength, and repeatable installation rather than unnecessary complexity.

About the Talley Steel Base for Winchester 70 (SA) (21.8 mm)

The Talley Steel Base for Winchester 70 (SA) (21.8 mm) is a traditional two-piece mounting solution for rifles that use the Winchester Model 70 short-action pattern with 21.8 mm front spacing. Its role is simple but important: it creates a stable interface between the rifle receiver and compatible Talley dovetail ring systems, giving the optic a firm platform before ring alignment and scope positioning are even considered.

The key advantage of this model is its steel construction. Compared with lighter alloy alternatives, steel is valued when the priority is a rigid, durable base that stands up well to repeated installation, recoil stress, and long-term field use. Talley’s 0 MOA configuration keeps the scope level with the receiver, which suits common hunting and general sporting applications where a neutral mounting angle is preferred. The black finish gives the base a subdued appearance that matches most rifles and optics without drawing attention.

Because this base is intended for use with Talley Dovetail Bases and compatible Talley ring systems, it suits shooters who want a conventional mounting arrangement with dependable mechanical engagement. On a Winchester Model 70 hunting rifle, that translates into a mount that prioritizes secure fit, resistance to movement under recoil, and a clean, low-profile installation that does not complicate the rifle’s handling.
