Talley Steel Base for Sako I, II, III, L461, L579, S491, M591, M85 SA (Extended)

• Steel construction: The all-steel build gives this Talley base the rigidity needed for a stable optic mounting platform, helping the scope stay aligned under repeated recoil and field use.
• Extended front-to-rear length: The extended pattern is 1/2″ longer than the standard base, which gives more flexibility when positioning scopes with shorter main tubes or when eye relief needs fine adjustment.
• Double recoil shoulder design: Talley’s base geometry is built to resist movement under recoil, which supports repeatable zero and reduces the chance of the mount shifting over time.
• Machined from solid bar stock: A one-piece machined steel base starts with dense material rather than a cast form, which helps maintain consistent fit and dependable contact with the rifle receiver.
• Made in USA: Built in the United States, this base reflects Talley’s focus on precise machining and close fit control for firearm-specific mounting applications.

About the Talley Bases Series

Talley Bases are Talley’s traditional scope-mount foundation for shooters who want a dedicated base system matched to specific rifle actions. The series covers a wide range of firearm models, and each base pattern is intended to fit the receiver it was designed for rather than serving as a generic compromise. That model-specific approach matters in hunting optics and general sporting use because a secure interface between rifle and optic is the starting point for dependable zero retention.

Within Talley’s lineup, steel bases represent the more classic two-piece mounting route, designed for use with Talley Fixed Rings or Talley Quick-Detachable Rings. Talley describes these bases as being machined from solid bar stock and built with double recoil shoulders, emphasizing strength, repeatability, and a close mechanical fit. The series is aimed at shooters who prefer a conventional base-and-ring arrangement, whether for a hunting rifle, a working field rifle, or a traditional sporting setup where durability and clean receiver fit matter more than unnecessary bulk.

About the Talley Steel Base for Sako I, II, III, L461, L579, S491, M591, M85 SA (Extended)

The Talley Steel Base for Sako I, II, III, L461, L579, S491, M591, M85 SA (Extended) is a firearm-specific mounting base made for Sako actions that use this dovetail-style footprint, giving the rifle a solid platform for a traditional ring-and-base optic setup. Its role is straightforward but important: it creates a rigid interface between receiver and rings so the riflescope can hold alignment through recoil, transport, and repeated use in the field.

What sets this version apart is its extended design. Talley states that the extended base is 1/2″ longer than the standard version, which is especially useful when mounting a scope with a shorter main tube or when extra adjustment room is needed to achieve proper eye relief. On rifles where scope placement can otherwise be restrictive, that additional length can make the difference between a compromised position and a clean, comfortable setup.

The base is built from steel, with a 4.00 mm height and 0 MOA inclination. In practice, that means it is suited to shooters who want a straightforward, level mounting solution rather than a canted long-range rail. The black finish keeps the appearance subdued and appropriate for classic hunting rifles, while Talley’s bar-stock machining and recoil-shoulder design focus on fit and stability. This base is intended for use with Talley Dovetail Bases ring systems and fits a broad group of compatible Sako models, making it a practical choice for maintaining a traditional low-profile rifle setup.

About Talley

Talley Manufacturing, Inc. is based in Santee, South Carolina, United States, and focuses on scope rings and firearm scope-mounting products. The company’s catalog covers fixed scope ring systems, lightweight alloy scope mounts, Picatinny rails, rimfire and specialty rings, screw-lock detachable rings, and related gunsmithing products. That specialization gives Talley a clear place in the optics market: it is not a general outdoor brand, but a maker centered on the mechanical side of mounting optics securely to firearms.

Talley states that its products are machined in the United States at its Santee plant. Across its range, the brand is known for practical mounting solutions that emphasize close fit, repeatability, and straightforward installation. For products such as steel bases, that reputation rests on model-specific designs and a preference for robust materials and precise machining rather than overly complex mounting systems.
