Rusan Modular Reduction Ring for Swarovski tM35 (M44x0.75)

• Modular system component: This reduction ring is part of the Rusan modular adapter system, letting a thermal clip-on setup be configured around the exact device interface needed instead of relying on a one-piece adapter.
• Made for Swarovski tM35: The M44x0.75 thread standard matches the Swarovski tM35 mounting interface, providing the correct mechanical connection for a secure and repeatable fit.
• Flexible multi-rifle use: In a modular clip-on setup, a dedicated reduction ring helps one thermal device work across different riflescope combinations with fewer parts to replace when equipment changes.
• Compact metal accessory: As a small, purpose-built adapter part, it adds the required interface without unnecessary bulk, helping keep a clip-on system practical in the field.
• Croatian-made construction: Built by Rusan in Croatia, it follows the company’s long-standing focus on precisely machined mounting components for hunting optics and clip-on devices.

About the Rusan Accessories Series

Rusan Accessories is the part of the Rusan-Mikron range dedicated to the small but critical components that make clip-on systems practical in real use. The series includes adapters and reduction rings for attaching night-vision and thermal clip-on devices to riflescopes, with both conventional and modular adapter systems available. That gives users a choice between a straightforward dedicated setup and a more flexible system built around interchangeable parts.

A defining idea behind the series is adaptability. The modular concept was developed so that one clip-on device can be shared across multiple rifles, or different clip-on devices can be matched with different riflescopes without rebuilding the entire mounting arrangement. This makes the series especially relevant for hunters and shooters who use thermal clip-ons in more than one rifle configuration. Alongside the adapter systems themselves, the range also includes accessory parts and spares that support long-term use. In practice, the series stands out for its focus on precise mechanical fit, compatibility with specific device standards, and a system-based approach rather than one-off mounting solutions.

About the Rusan Modular Reduction Ring for Swarovski tM35 (M44x0.75)

The Rusan Modular Reduction Ring for Swarovski tM35 (M44x0.75) is a dedicated interface part for users building a modular thermal clip-on setup around the Swarovski tM35 mounting standard. Rather than acting as a complete adapter on its own, it performs a more specific role: it provides the correct thread interface so the modular system can be matched to this particular clip-on platform. That matters because clip-on performance depends not only on the device itself, but also on how consistently and accurately it is connected to the rest of the mounting system.

Within a modular arrangement, a part like this makes the setup more versatile. A user can keep the broader adapter system and change only the interface component needed for a given device standard, which is more practical than replacing an entire mount assembly. For owners of the Swarovski tM35, the M44x0.75 thread specification ensures the ring is built for the correct connection point, helping maintain secure alignment between the clip-on and the adapter components behind it.

Its role is simple, but important: reduce complexity in a modular build while preserving compatibility. Finished in black and made by Rusan in Croatia, it fits the company’s broader design approach of producing purpose-built mounting parts for thermal and night-vision equipment where repeatable fit and mechanical reliability matter more than unnecessary complexity.

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 is important because it explains why Rusan is best known for precisely machined mounting solutions rather than general sporting goods.

Today, the company manufactures scope mounts, scope rings, Picatinny rails, and firearm tuning products, and it is especially well established in adapters for clip-on devices. Rusan introduced its original clip-on sight adapter clamp in 2009, then expanded into modular systems for night-vision and thermal-imaging equipment. This long specialization in the mechanical side of optics mounting gives the brand a strong reputation among users who need dependable alignment, repeatable attachment, and broad compatibility across riflescopes and clip-on platforms.
