Rusan Modular Reduction Ring for Dedal (M52x0.75)

• Dedal M52x0.75 interface: This reduction ring is made specifically for the Dedal mounting standard (M52x0.75), giving a correct thread match for modular clip-on setups and helping avoid improvised fitment.
• Modular clip-on integration: As part of the Rusan modular adapter system, it helps connect a thermal clip-on device into a configurable mounting setup, making it easier to adapt equipment to different riflescopes or rifles.
• Steel construction: The steel body adds durability where threads and repeated installation matter most, supporting long service life in field use and reducing wear from frequent mounting changes.
• Compact, low-mass design: With a weight of 0.07 kg, it adds only minimal bulk to the adapter assembly, helping preserve the handling balance of a hunting or observation rifle.
• Purpose-built accessory: Finished in black and designed for thermal clip-on applications, it fits naturally into professional clip-on systems where secure mechanical compatibility matters more than unnecessary complexity.

About the Rusan Accessories Series

Rusan Accessories is the part of the Rusan-Mikron range focused on the practical hardware needed to integrate night-vision and thermal clip-on devices with riflescopes and rifles. The series includes adapters, reduction rings, spare parts and related mounting components, giving users a system-based approach rather than isolated parts. A key idea behind the range is flexibility: Rusan offers both conventional and modular adapter systems, so the same clip-on device can be configured for different rifles or paired with different optics more efficiently.

The series reflects Rusan’s long involvement with clip-on mounting solutions, including the company’s adapter designs that entered the global market in 2009 and the later development of its modular-adapter prototype in 2020. In practice, that makes the line especially relevant for hunters and shooters who need a dependable mechanical interface between premium optics and add-on thermal equipment. Rather than adding electronic features, these accessories focus on precise fit, repeatable attachment and compatibility across different device standards. That makes the series particularly useful wherever a clip-on setup must remain adaptable without replacing the entire mounting solution.

About the Rusan Modular Reduction Ring for Dedal (M52x0.75)

The Rusan Modular Reduction Ring for Dedal (M52x0.75) is a dedicated accessory for users building or maintaining a modular thermal clip-on setup around the Dedal thread standard. Its main job is straightforward but important: it provides the correct mechanical interface for equipment that uses the M52x0.75 thread, allowing the rest of the adapter system to seat properly and work as intended. In clip-on use, correct thread geometry matters because even a small mismatch can affect alignment, mounting security and the ease of repeated installation.

Rusan builds this model from steel, which suits a part that is repeatedly threaded on and off and must retain its shape over time. That material choice is especially relevant in field conditions where accessories are handled with gloves, exposed to dirt or moisture, and moved between rifles or optics. At 0.07 kg, the ring remains light enough that it does not noticeably burden the overall clip-on assembly, yet it still provides the solid feel expected from a structural adapter component.

Because it belongs to the Rusan modular system, this reduction ring is most useful for shooters who want a more configurable mounting solution instead of a fixed one-piece arrangement. It is not a general-purpose spacer, but a purpose-built connection part for thermal clip-on integration, where secure fit, repeatability and compatibility with the Dedal standard are the priorities.

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 Rusan’s reputation in the optics market is built on mechanical products rather than electronics: mounts, rings, Picatinny rails and firearm-related fitting components.

The company is particularly well known for adapter clamps for clip-on sights and for accessories used with night-vision and thermal-imaging devices. Rusan introduced its clip-on sight adapter clamp in 2009, and that specialization remains central to the brand. In practical terms, Rusan’s products are valued for solving compatibility and mounting problems between rifles, riflescopes and add-on observation devices, which makes the brand especially relevant in hunting optics and thermal clip-on applications.
