Optilock Sako Long Base, Stainless Steel

• Steel base construction: The base is made from steel, giving the scope mounting system the rigidity needed to keep alignment stable under recoil and repeated field use.
• Long-base format for Sako actions: The long configuration is intended for compatible long-action and magnum-length Sako rifles, helping provide correct ring spacing and a secure platform for larger hunting optics.
• Stainless steel finish: The stainless construction suits stainless rifles and adds practical corrosion resistance for use in wet weather, mountain hunting, and general outdoor carry.
• Optilock system compatibility: This base is designed to work with Optilock rings, so it forms part of a matched mounting system built for reliable scope fit and repeatable positioning.
• Low 8.00 mm base height: The BH height helps keep the optic mounted close to the bore, which supports a more natural cheek weld and a more consistent shooting position.

About the Optilock Series

Optilock is Sako’s dedicated line of scope mounting components, developed for shooters who want a mounting system matched to the rifle rather than a generic aftermarket solution. The series includes bases, rings, and complete mounting options for compatible Sako and Tikka rifles, with versions made for different receiver interfaces, scope tube diameters, and mounting heights. That broad fitment makes the system suitable for everything from compact hunting optics to larger scopes used for longer-range work.

A defining feature of the series is its emphasis on precise steel construction and secure scope support. Optilock bases and rings are machined from steel, with models offered in CrMo alloy or stainless steel depending on the application and rifle finish. In ring-equipped setups, the system is also known for its polymer inserts, which help distribute clamping force more evenly around the scope tube and reduce the risk of marking the optic. In practical use, the Optilock family is aimed at hunters and rifle owners who want a durable, rifle-specific mounting solution that supports consistent zero retention and a clean mechanical fit.

About the Optilock Sako Long Base, Stainless Steel

The Optilock Sako Long Base, Stainless Steel is a fixed scope base built for a range of compatible Sako long and medium-length actions, including selected Sako 75, Sako 85, classic L-series, and TRG-S variants. Its role is straightforward but important: it creates the solid interface between rifle and rings, which is the foundation for dependable sight alignment and repeatable accuracy. For hunting rifles that may be carried over long distances, exposed to weather, and fired from improvised positions, that stability matters as much as the scope itself.

This model uses a steel body, which gives the base the stiffness needed to resist movement and maintain a secure connection under recoil. The stainless steel construction is especially well suited to rifles used in damp forests, open mountain terrain, or coastal conditions, where corrosion resistance is a practical advantage rather than a cosmetic detail. Its 8.00 mm BH height helps keep the optic low over the receiver, supporting a more natural head position and better consistency behind the rifle.

Because it is part of the Optilock mounting system, this base is intended to be paired with compatible Optilock rings. That gives the shooter a mounting setup designed around Sako rifle geometry, with ring spacing and fit that suit the action length. For traditional hunting rifles and stainless field builds, this long base offers a strong, clean, and purpose-built mounting platform.

About Optilock

Optilock is Sako’s line of rifle scope mounts, bases, and rings, created specifically for use with Sako and Tikka rifles. The system is built around rifle-specific fit and a mechanically secure interface, rather than a one-size-fits-all approach. Across the range, Optilock bases are offered for compatible rifle interfaces, including dovetail and Picatinny rail formats, while rings are available in different diameters and heights to suit different scopes.

A key part of the Optilock concept is its use of steel construction, with bases and rings machined in CrMo alloy or stainless steel versions depending on the model. Optilock ring designs also use polymer inserts around the scope tube. These inserts help spread clamping force more evenly and reduce the chance of marking the optic, which is especially relevant on quality hunting scopes. In practice, Optilock has a reputation for giving Sako and Tikka owners a mounting solution that matches the rifle properly and supports stable zero retention in the field.
