Osuma Pair of Rings for Osuma Base, 36 mm

• 36 mm ring size: Built for 36 mm scope tubes, these rings provide the correct fit for larger optics and help maintain even clamping without improvised inserts or adapters.
• Osuma Base interface: Designed for the Osuma Base system, the rings form part of a dedicated mounting setup that keeps the scope and base matched for straightforward installation.
• Aluminium construction: The aluminium body keeps weight under control while still providing the rigidity needed for a stable riflescope mounting platform.
• Black finish: The black surface gives the rings a discreet appearance and matches common hunting optics and tactical optics setups.
• Finnish-made design: Designed and manufactured in Finland, these rings reflect Osuma’s focus on practical scope-mount components for field and range use.

About the Osuma Osuma Base Rings Series

Osuma Osuma Base Rings are part of the brand’s fixed scope-mount system, developed to work with Osuma bases as a dedicated three-part assembly of base, bottom ring and top ring. This approach gives the series a clear role within the Osuma lineup: it is intended for shooters who want a straightforward, modular mounting solution built around compatible components rather than a one-piece universal design.

The series is made from high-grade aluminium with an anodized surface, combining low weight with the durability expected from rifle scope mounting hardware. Osuma offers these rings in several tube sizes, including 1 inch, 30 mm, 34 mm, 36 mm and 40 mm, and the range also includes low, medium and high height options where available. That breadth makes the series suitable for different riflescope formats, from conventional hunting optics to larger precision-oriented scopes. Designed and manufactured in Finland, the Osuma Base Rings series reflects a practical design philosophy focused on secure scope support, clean integration with the base system and compatibility across several rail and rifle-platform mounting arrangements.

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

The Osuma Pair of Rings for Osuma Base, 36 mm is a category-specific mounting component for shooters using a 36 mm riflescope tube within the Osuma Base system. Its main advantage is precise compatibility: instead of adapting a scope to an unsuitable ring diameter, this pair is built for the correct tube size from the outset. That matters in practice because proper ring fit helps distribute clamping force more evenly and supports consistent scope alignment.

As part of the Osuma fixed mount system, these rings are intended to work with bases that use the Ø 7 mm interface, including Osuma, EAW, Optilock and Recknagel-compatible arrangements listed for this model. This makes them useful for shooters who already have a compatible base and need the correct upper ring section for a larger-tube optic. The KR 0.0 mm extension keeps the setup neutral, which suits conventional scope positioning where no forward or rearward offset is required from the ring itself.

The rings are made from aluminium, a sensible choice for keeping overall rifle weight manageable while still providing the stiffness needed in a scope-mounting component. Finished in black, they integrate neatly with most riflescopes and rifles without drawing attention to the mounting hardware. For hunting rifles and range setups alike, this Osuma ring pair is a practical solution when the priority is a clean, correctly matched 36 mm mounting interface.

About Osuma

Osuma is a Finland-based brand whose history goes back to the early 1990s, when its owner began developing scope mounts for his own hunting and benchrest shooting needs. That origin is still visible in the company’s product focus: Osuma’s main area of expertise is rifle scope mounting, with a range that includes scope mounts, scope rings, rail mounts, red-dot and holosight mounts, and suppressors.

The company designs and manufactures its products in Finland, and its scope rings are described as aluminium components with an anodized surface. Osuma’s catalog has grown to more than 150 products, and the brand remains closely tied to practical shooting applications rather than broad outdoor equipment production. With the business having passed from father to son, Osuma has maintained a concentrated approach to mounting solutions across systems such as 11 mm, Tikka 17 mm, Sako, Picatinny, Optilock and Blaser.
