Rusan Modular Adapter for Swarovski tM35

• Modular TM35 interface: Built for the Swarovski tM35 mounting standard (M44x0.75), this adapter forms the link between the clip-on and the riflescope-side clamp, making the thermal device easier to move between suitable optics.
• Broad eyepiece compatibility: The system works with a wide range of rear diameters from 30 mm to 67 mm, so one thermal clip-on setup can be matched to many common riflescope housings.
• Steel construction: The steel body gives the adapter the rigidity needed for a secure connection, which matters when a clip-on device must stay aligned during repeated mounting and field use.
• Orientation-capable design: As part of Rusan’s modular concept for the tM35 platform, the adapter supports correct device positioning, helping keep the thermal image properly aligned with the day optic.
• Purpose-built for thermal clip-ons: Instead of a generic ring, this adapter is made specifically for thermal clip-on use, which simplifies building a repeatable front-mounted hunting optics setup.

About the Rusan Accessories Series

Rusan Accessories covers the company’s supporting hardware for mounting and adapting optics, with a strong focus on connecting night-vision and thermal clip-on devices to conventional riflescopes. Within this family, Rusan offers both conventional and modular adapter systems, giving users a choice between a straightforward dedicated setup and a more flexible arrangement for multiple rifles or multiple devices.

The series is built around practical field use. A modular arrangement lets the user keep one part of the system matched to the clip-on while pairing it with different riflescope-side components as needed. That approach is especially useful for hunters and other shooters who run the same thermal unit on more than one rifle. Rusan’s accessory range also includes reduction rings and model-specific interface parts, so the system can be tailored to particular clip-on standards rather than forced into a one-size-fits-all solution. Across the series, the emphasis is on mechanical fit, repeatable positioning, and compatibility with the wide variety of scope diameters found in real use.

About the Rusan Modular Adapter for Swarovski tM35

The Rusan Modular Adapter for Swarovski tM35 is the device-side connector for shooters who want to integrate a Swarovski tM35 thermal clip-on into Rusan’s modular mounting system. Its defining feature is the M44x0.75 interface, which matches the tM35 mounting standard and creates the front half of a modular setup. In practice, that means the clip-on can be paired with the appropriate riflescope-side clamp diameter instead of relying on a fixed one-piece adapter tied to only one optic.

This is a practical solution for users who alternate between riflescopes with different outer dimensions. The adapter is compatible with rear clamp sizes including 30 mm, 34 mm, 36 mm, 47 mm, 48 mm, 50 mm, 51 mm, 52 mm, 53 mm, 54 mm, 56 mm, 57 mm, 58 mm, 58.4 mm, 59 mm, 60 mm, 61 mm, 62 mm, 63 mm, 63.5 mm, 64 mm, 65 mm, 66 mm, and 67 mm. That range makes it easier to build one thermal clip-on system around several day optics, provided the correct companion clamp is used.

Steel construction is an important part of the design because a clip-on adapter has to do more than simply fit; it must hold the device firmly and maintain alignment under regular handling. Finished in black, the adapter stays visually discreet on a hunting or observation setup. For users of the Swarovski tM35 platform, this Rusan component is a focused mechanical part: it is not a universal ring, but a dedicated connector intended to make a modular thermal clip-on arrangement more adaptable and easier to configure.

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, establishing the mechanical foundation for the product categories it is known for today.

The company specializes in scope mounts, scope rings, Picatinny rails, and firearm tuning products, alongside adapters for night-vision and thermal-imaging devices. Rusan is particularly well known for its clip-on adapter systems, including adapter clamps that entered the global market in 2009. That background is directly relevant here: products such as the modular adapter for the Swarovski tM35 come from a manufacturer whose core expertise is not electronics, but the precision-machined interface between the firearm, the riflescope, and the clip-on device.
