Rusan Modular adapter reducing ring for Rusan Eyepiece (M35x0.75)

• Modular connector interface: This reducing ring links a compatible Rusan eyepiece to the Rusan modular adapter system, making it easier to configure a clip-on setup around the device and riflescope combination in use.
• M35x0.75 eyepiece thread fit: The ring is made for Rusan eyepieces with an M35x0.75 thread, giving a correct mechanical match that helps maintain secure attachment and consistent alignment.
• Part of the modular adapter system: As a component in the modular range, it supports a more flexible setup where one clip-on device can be shared across different rifles or paired with different optical accessories.
• Compact accessory format: A reducing ring adds the required interface without the bulk of a full adapter body, which helps keep the overall clip-on arrangement simple and efficient.
• Croatian-made metal accessory: Built by Rusan in Croatia, it reflects the company’s focus on practical mounting and adapter components for night-vision and thermal clip-on use.

About the Rusan Accessories Series

Rusan Accessories is the part of the Rusan range dedicated to the small but essential components that make clip-on systems practical in the field. The series includes adapters and reduction rings for connecting night-vision and thermal clip-on devices to riflescopes, with both conventional and modular adapter solutions available. That modular approach is especially useful for shooters who want to use one clip-on device with multiple rifles or adapt different devices to different optics without rebuilding the whole interface each time.

Within the series, the emphasis is on mechanical compatibility, repeatable fit, and a logical system of connectors, rings, and accessories that work together as a complete mounting solution. Rusan introduced its original adapter for connecting riflescopes and night-vision clip-on devices to the global market in 2009, and the first modular-adapter prototype followed in 2020. The result is a product family built around practical field use: adapting thread standards, simplifying equipment changes, and helping clip-on users assemble a setup that suits hunting optics and thermal or night-vision applications.

About the Rusan Modular adapter reducing ring for Rusan Eyepiece (M35x0.75)

The Rusan Modular adapter reducing ring for Rusan Eyepiece (M35x0.75) is a specialized interface part for users building or expanding a Rusan modular adapter setup. Its role is straightforward but important: it provides the correct connection for a Rusan eyepiece with M35x0.75 thread, allowing that eyepiece to integrate properly with the modular connector system. In a clip-on configuration, that kind of exact thread compatibility matters because it helps the system assemble cleanly and reduces the chance of mismatch between components.

As a reducing ring rather than a complete adapter body, this accessory is aimed at users who already understand the logic of modular clip-on equipment and need the correct interface piece for a specific eyepiece standard. That makes it particularly relevant for thermal imaging or night-vision users who want to keep their equipment adaptable across more than one rifle or optical arrangement. Instead of relying on a fixed one-piece solution, the modular system lets the setup be tailored component by component.

Finished in black and made by Rusan in Croatia, this accessory fits naturally into the company’s broader ecosystem of clip-on adapters, mounts, and rails. For the user, the practical benefit is a cleaner path to compatibility: the right thread interface in the right place, so the rest of the modular assembly can do its job correctly.

About Rusan

Rusan-Mikron is a Croatian manufacturer based in Marija Bistrica, with roots in the Rusan family’s metalworking business dating back to 1983. Željko Rusan opened a gunsmith shop in 1986, and the company began producing scope mounts in 1993. That background helps explain why Rusan is closely associated with practical mounting solutions and firearm-related metal components.

Today, Rusan manufactures scope mounts, scope rings, Picatinny rails, adapter clamps, and related firearm tuning products. The company is particularly well known for adapter systems for night-vision and thermal-imaging devices, including the clip-on sight adapter clamp it introduced in 2009. Its product range also covers rails for rifle platforms such as Tikka T3, Sauer 202, and Zastava M70, reflecting a strong focus on fit, compatibility, and mechanically sound interfaces for sporting and hunting optics.
