Osuma Pair of Rings for Optilock Base, 36 mm

• Optilock-base compatibility: Built for the Ø 7 mm Optilock-style interface, these rings fit the matching base system securely and make it easier to keep a scope aligned on rifles already set up for this mounting standard.
• 36 mm scope fit: The 36 mm ring diameter supports large-tube optics that are often chosen for specialist long-range or low-light setups where extra internal adjustment and robust construction matter.
• Aluminium construction: The aluminium body keeps weight under control while still providing the rigidity needed for a stable riflescope mounting solution in regular hunting and range use.
• Anodized black finish: The black anodized surface helps resist everyday wear and handling marks, while also giving the rings a subdued appearance that matches most rifles and optics.
• Made in Finland: Finnish manufacture reflects a design approach focused on practical fit, clean machining and compatibility with common European scope-mounting systems.

About the Osuma Optilock Base Rings Series

Osuma Optilock Base Rings are designed as a dedicated ring family for rifles already equipped with original Optilock-style bases. Within Osuma’s mounting range, this series serves shooters who want a straightforward way to mount modern optics without changing the underlying base system. The line covers several common tube diameters, including 30 mm, 34 mm, 36 mm and 40 mm, with selected sizes offered in different heights so the scope can be matched more closely to the rifle and objective bell.

A defining characteristic of the series is its focus on practical compatibility rather than universal adaptation. These rings are made from high-grade aluminium and finished with an anodized surface, giving them a combination of low weight, corrosion resistance and everyday durability that suits hunting rifles and general sporting use. Because the rings are sold in pairs and built around the Optilock-base pattern, the series is especially relevant for shooters who want to retain an existing mounting platform while moving to a different optic tube diameter. In short, the Osuma Optilock Base Rings series is aimed at clean, purpose-built riflescope installation with minimal unnecessary bulk.

About the Osuma Pair of Rings for Optilock Base, 36 mm

The Osuma Pair of Rings for Optilock Base, 36 mm is a specialist mounting solution for riflescopes with a 36 mm main tube. That tube size is typically found on larger, more specialized optics, so the role of these rings is not simply to hold a scope in place, but to provide a stable connection between a substantial optic and an Optilock-style base system. For shooters who already use this interface, the design keeps the installation consistent without requiring a change to the rifle’s existing base arrangement.

The ring set uses an aluminium construction, which helps reduce unnecessary weight on the rifle while still offering the stiffness needed for dependable scope support. In practice, that matters on hunting rifles carried over longer distances and on range rifles where balanced handling is still important. The KR 0.0 mm extension indicates a non-extended configuration, making this pair suitable where standard ring positioning provides the correct eye relief and scope placement. Its black finish keeps the appearance discreet and coordinates easily with most riflescope bodies and base systems.

Compatibility is a key part of this model’s appeal. It is intended for the Ø 7 mm interface used by Optilock, Osuma, EAW and Recknagel base patterns in this format, which gives it practical relevance for shooters working within established European mounting standards. For a 36 mm optic, that combination of dedicated fit, low weight and system-specific compatibility makes these rings a sensible choice where a clean and mechanically straightforward mounting setup is the priority.

About Osuma

Osuma is a Finland-based brand focused primarily on riflescope mounting. Its history goes back to the early 1990s, when the company’s owner developed the first mounts for his own hunting and benchrest shooting needs. That background still shows in the product range, which centers on practical mounting components rather than broad general shooting equipment.

Today, Osuma’s catalogue includes scope mounts, scope rings, rail mounts, red-dot and holosight mounts, suppressors and accessories. The brand is particularly associated with compatibility across common European rifle and mounting standards, with rail mounts offered for systems such as 11 mm, Tikka 17 mm, Sako, Picatinny, Optilock and Blaser. Osuma products are designed and manufactured in Finland, and the company remains a family business that has passed from father to son. In this category, its reputation rests on straightforward engineering, broad fitment coverage and a clear specialization in mounting solutions.
