Rusan reducing ring for HIKMICRO Thunder TH35C

• Dedicated interface for HIKMICRO Thunder TH35C: This reducing ring matches the Hikmicro Thunder bayonet mounting standard on the device side, giving a correct mechanical connection point for a compatible clip-on setup.
• M52x0.75 adapter-side thread: The ring reduces from the Dedal mounting standard (M52x0.75), allowing the clip-on system to integrate with the corresponding Rusan adapter architecture instead of relying on improvised fitment.
• Steel construction: A steel body helps maintain thread integrity and alignment under repeated installation and removal, which matters for clip-on use where consistent positioning is important.
• Modular adapter concept: As part of the Rusan Accessories range, this ring lets one clip-on mounting system be configured for a specific device interface, making it easier to build a practical multi-component setup.
• Purpose-built accessory: This is a thread reducing ring, not a complete adapter, so it is intended for users who need the correct intermediate part to assemble a full clip-on adapter with a compatible Rusan Q-R adapter.

About the Rusan Accessories Series

Rusan Accessories is the part of the Rusan-Mikron range dedicated to the small but essential components that make clip-on systems practical in the field. The series covers adapters and reduction rings for night-vision and thermal clip-on devices, along with related adapter accessories and spare parts, so users can configure a mounting solution around a specific riflescope and clip-on combination. This product family sits alongside the company’s mounts, rings, and rails, but its role is more specialized: it solves the interface between different attachment standards.

A key idea behind the series is modularity. Rusan offers both conventional and modular adapter systems, and the accessory range supports that approach by letting one clip-on device be shared across multiple rifles or matched to different optics with the correct intermediate parts. Rusan states that its original adapter for connecting riflescopes and night-vision clip-on devices entered the global market in 2009, while the first modular-adapter prototype was completed in 2020. In practice, the series is aimed at hunters and other users who need a secure, repeatable way to connect thermal or night-vision equipment without replacing an entire mounting system each time the device interface changes.

About the Rusan reducing ring for HIKMICRO Thunder TH35C

The Rusan reducing ring for HIKMICRO Thunder TH35C is a dedicated interface component for building a clip-on mounting solution around a Hikmicro Thunder bayonet connection. Its job is straightforward but important: it converts the adapter side from the Dedal-standard M52x0.75 thread to the mounting standard used by the compatible HIKMICRO Thunder device family. That makes it a key part for users who already work within the Rusan adapter ecosystem and need the correct device-side connection rather than a one-piece dedicated mount.

Because this part is made from steel, it is suited to repeated assembly and disassembly without the more rapid wear that can affect softer materials. For clip-on thermal use, that matters because the interface between the day optic, adapter and clip-on device needs to stay mechanically consistent. A reducing ring like this also keeps the setup more flexible: instead of replacing the whole adapter when changing device standards, the user can configure the system with the correct ring and the appropriate Rusan Q-R adapter.

This accessory is intended specifically for thermal clip-on applications and should be understood as one part of a larger mounting solution. It does not function as a complete adapter on its own. In practical terms, it is the correct choice for users assembling a Rusan-based clip-on system for a compatible HIKMICRO Thunder unit and who need a precise, purpose-built connection between the device and the adapter body.

About Rusan

Rusan-Mikron is a Croatian manufacturer based in Marija Bistrica, Croatia, 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 reflected in a product range centered on practical firearm-interface components rather than general outdoor optics.

Today, Rusan is known for manufacturing scope mounts, scope rings, Picatinny rails, and firearm tuning products, along with adapter clamps for night-vision and thermal-imaging devices. The company introduced its clip-on sight adapter clamp in 2009, a milestone that remains especially relevant for hunters and shooters using front-mounted thermal or night-vision systems. In this category, Rusan’s reputation is built on making the mechanical connection between rifle, optic and add-on device secure, repeatable and adaptable across different platforms.
