Rusan Reduction Ring for Dipol DN 33/34 (M49x0.75)

• M52x0.75 to M49x0.75 reduction: This ring adapts a Rusan conventional M52 system to clip-on devices that use the Dipol M49x0.75 thread, making it possible to build the correct interface without replacing the whole adapter setup.
• Built for thermal clip-on use: Designed for thermal clip-on applications, it helps keep the attachment system matched to the device thread standard so alignment and fit remain consistent in field use.
• Steel construction: The steel body gives the ring the rigidity needed for repeated mounting and removal, which matters when a clip-on system must stay secure under regular handling.
• Counter nut and wrench included: The supplied counter nut and wrench simplify installation and positioning, so the ring can be fitted correctly as part of a complete adapter assembly.
• Modular compatibility path: This is a dedicated thread reducing ring, allowing owners of compatible Dipol devices to pair them with the appropriate Rusan Q-R adapter instead of sourcing a separate one-piece solution.

About the Rusan Accessories Series

Rusan Accessories is the part of the Rusan-Mikron range focused on the practical hardware that connects optics and clip-on devices into a usable field setup. The series includes adapters and reduction rings for attaching night-vision and thermal clip-on devices to riflescopes, alongside related mounting components. A key idea behind the range is flexibility: Rusan offers both conventional and modular adapter systems, so users can choose a straightforward fixed-format solution or build a system around multiple riflescopes and devices.

Within the series, reduction rings play an important role because they bridge different thread standards between the clip-on unit and the adapter body. That makes the family especially relevant for hunters and shooters who already own a clip-on device but need a clean mechanical match to a riflescope adapter. Rusan’s original adapter for connecting riflescopes and night-vision clip-on devices entered the global market in 2009, and the company later expanded the concept with a modular-adapter prototype completed in 2020. The result is an accessories line built around compatibility, repeatable fit, and the ability to configure one mounting system around real-world device combinations.

About the Rusan Reduction Ring for Dipol DN 33/34 (M49x0.75)

The Rusan Reduction Ring for Dipol DN 33/34 (M49x0.75) is a dedicated adapter component for users who need to connect a compatible Dipol-thread clip-on device to the Rusan conventional M52 adapter platform. Its job is specific but important: it reduces the thread from M52x0.75 on the adapter side to M49x0.75 on the clip-on side, allowing the correct mechanical interface for devices built around the Dipol mounting standard.

In practice, this kind of ring is useful when building a clip-on setup around existing equipment rather than replacing the whole mounting solution. It lets the user keep the main Rusan adapter architecture and simply match the thread standard required by the device. That is especially relevant for thermal clip-on use, where secure fit and correct positioning matter for reliable attachment and repeatable handling. The included counter nut helps with proper installation, while the supplied wrench makes assembly more straightforward.

This model is suitable for devices using the M49x0.75 Dipol thread, including Dipol DN 33/34 and Dipol TFA1200. It is important to note that this product is only a thread reducing ring, not a complete clip-on adapter by itself. To create a full working assembly, it must be combined with the appropriate Rusan Q-R adapter in the correct size for the day scope.

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, establishing the mechanical focus that still defines the brand today. Its product range includes scope mounts, scope rings, Picatinny rails, firearm tuning products, and adapter systems for optical devices.

Rusan is particularly well known for its work in the interface between riflescopes and clip-on technology. The company introduced its clip-on sight adapter clamp in 2009 and has since developed adapters for night-vision and thermal-imaging devices alongside rails for rifle platforms such as the Tikka T3, Sauer 202, and Zastava M70. That background is directly relevant here: products like this reduction ring come from a manufacturer with long experience in precision-machined mounting solutions for hunting optics and clip-on systems.
