About the Osuma Osuma Base Rings Series

Osuma Osuma Base Rings are part of the brand’s fixed scope-mount system, designed to work with Osuma bases in a modular three-part arrangement of base, bottom ring and top ring. This approach gives shooters a clear, system-based way to build a riflescope mount around the rifle and optic they already use, rather than relying on a one-piece solution that may not suit every setup.

The series is aimed at hunters and target shooters who want a practical, mechanically simple mounting option with the consistency of a fixed design. Designed and manufactured in Finland, these rings follow Osuma’s preference for high-grade aluminium with an anodized surface, balancing low weight with the durability expected from everyday rifle use. The range covers several common tube diameters, including 1 inch, 30 mm, 34 mm, 36 mm and 40 mm, and is offered in different height variants depending on the model. Within the Osuma lineup, the series serves as a flexible bridge between the rifle-specific base and the optic, making it relevant for both traditional hunting rifles and more specialized shooting platforms.

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

Osuma Pair of Rings for Osuma Base, 34 mm is intended for shooters who need a fixed upper ring set for a 34 mm riflescope tube within the Osuma mounting system. That tube size is common on scopes with larger adjustment ranges, larger erector assemblies or more demanding long-range and low-light applications, so these rings are well suited to modern hunting optics and precision-oriented riflescope setups.

The design focuses on compatibility and mechanical simplicity. As part of the Osuma Base Rings family, this pair integrates into a mount built around a separate base and lower interface, which makes it easier to configure the rifle around the chosen optic and mounting standard. The listed KR 0.0 mm extension indicates a neutral configuration, useful when the scope can be positioned correctly without additional forward or rearward offset.

Construction in aluminium keeps the rings light enough for field rifles while still providing the stiffness needed to hold scope alignment under regular use. The black finish gives the rings a subdued appearance and adds surface protection against handling wear and outdoor exposure. Compatibility with EAW, Optilock, Osuma and Recknagel Ø 7 mm interfaces also makes this model relevant for shooters using established European base standards and looking for a 34 mm upper ring solution that stays within that ecosystem.

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. Rifle scope mounting remains the company’s main area of expertise, and that focus is reflected in a product range that includes scope mounts, scope rings, rail mounts, red-dot and holosight mounts, and suppressors.

The brand is known for designing and manufacturing its products in Finland and for maintaining a practical, shooter-led approach to product development. Its scope rings are made from aluminum with an anodized surface, and the wider lineup covers mounting solutions for systems such as 11 mm, Tikka 17 mm, Sako, Picatinny, Optilock and Blaser. Osuma’s business has also passed from father to son, which reinforces the company’s long-standing specialization in this category.
