Osuma Pair of Rings for Optilock Base, 34 mm

• Optilock-base fit: Built for original Optilock bases with a Ø 7 mm interface, these rings provide a straightforward way to mount a 34 mm scope without changing the base system already on the rifle.
• 34 mm scope support: The 34 mm ring diameter suits modern riflescopes with larger main tubes, helping accommodate optics that offer broader adjustment range and more robust internal construction.
• Aluminium construction: Made from aluminium, the rings keep weight down while still giving the rigidity needed for a secure scope-to-rifle connection in regular hunting and range use.
• Anodized black finish: The black anodized surface adds wear resistance and helps the rings maintain a clean, low-reflection appearance that matches most rifles and optics.
• Sold as a pair: Supplied as a matched pair of rings, the set gives the two upper mounting points needed to complete a compatible Optilock-style scope mounting setup.

About the Osuma Optilock Base Rings Series

Osuma Optilock Base Rings are designed for shooters who want to use original Optilock mounting bases while choosing ring sizes that match today’s wider range of riflescopes. The series is built around compatibility with the Optilock-style base interface, making it a practical option for rifles already set up around that mounting standard. Across the range, the rings are sold in pairs and cover several common tube diameters, including 30 mm, 34 mm, 36 mm and 40 mm, with selected height options depending on size.

A defining characteristic of the series is its focus on a simple, purpose-built design. High-grade aluminium construction keeps the rings light without moving away from the stiffness expected in a scope mount, while the anodized surface improves resistance to handling wear and field use. Within Osuma’s lineup, this series suits hunters and target shooters who prefer a separate ring-and-base arrangement rather than a one-piece mount. The result is a family of mounts that emphasizes fit with the Optilock platform, sensible material choice, and straightforward integration with larger modern scope tubes.

About the Osuma Pair of Rings for Optilock Base, 34 mm

The Osuma Pair of Rings for Optilock Base, 34 mm is intended for rifles fitted with an Optilock-compatible Ø 7 mm base interface and for scopes built on a 34 mm main tube. That combination makes it especially relevant for current hunting optics and precision-oriented riflescopes, where 34 mm tubes are often chosen to allow greater internal adjustment travel or a stronger scope body. By matching that tube size correctly, the rings provide the proper clamping format without forcing compromises through inserts or adapters.

This model uses an aluminium body, which helps keep the mounting setup lighter than steel alternatives while still suiting normal field and range applications. On a hunting rifle, that matters because unnecessary weight accumulates quickly once a larger optic, bases and accessories are installed. The black finish keeps the appearance discreet and consistent with most riflescopes and actions, while also adding surface protection for repeated installation and removal.

As part of the Osuma Optilock Base Rings family, this version is about maintaining an existing base standard while moving to a larger optic tube diameter. It is a practical choice when the rifle already uses the Optilock-style system and the goal is a clean, dedicated ring set rather than replacing the entire mount arrangement. The KR 0.0 mm extension indicates a non-extended format, which suits conventional scope positioning where the rifle and optic already provide the needed eye-relief placement.

About Osuma

Osuma is a Finland-based brand whose history goes back to the early 1990s, when its owner developed the first scope mounts for his own hunting and benchrest shooting needs. The company later passed from father to son, and rifle scope mounting remains its core area of expertise. That specialization is reflected in a product range centered on practical shooting hardware rather than broad outdoor equipment.

Osuma designs and manufactures its products in Finland. Its lineup includes scope mounts, scope rings, rail mounts, red-dot and holosight mounts, and suppressors, with mounting solutions for systems such as 11 mm, Tikka 17 mm, Sako, Picatinny, Optilock and Blaser. In this category, Osuma is particularly known for aluminium scope rings with an anodized surface and for offering a wide selection of mounting options built around specific rifle and base standards.
