Rusan Extension Ring for Dedal 552

• Dedal 552 thread compatibility: The ring is built for the Dedal mounting standard (M52x0.75), giving a correct mechanical interface for compatible thermal clip-on setups and helping maintain secure alignment between components.
• Steel construction: A steel body gives the extension ring the rigidity needed for mounting applications, reducing flex and supporting a stable connection in field use.
• Compact, low-mass design: At 50.00 g, the ring adds only modest weight to the front of the system, helping preserve the handling balance of a clip-on-equipped rifle.
• Purpose-built for thermal clip-ons: Designed as an accessory for thermal clip-on devices, it supports integration of compatible equipment without resorting to improvised spacers or non-matching thread solutions.
• Protective black finish: The black finish keeps the part visually discreet on a hunting or tactical optics setup and suits the appearance of modern clip-on adapters and mounts.

About the Rusan Accessories Series

Rusan Accessories is the supporting hardware range developed by Rusan-Mikron for users who need to adapt, extend, or configure optical mounting systems around night-vision and thermal clip-on devices. The series centers on practical interface parts such as adapters and reduction rings, with a focus on making different devices and riflescope combinations work together in a controlled, repeatable way. That matters in the field, where a small part often determines whether a clip-on setup mounts cleanly and stays correctly oriented.

The series includes both conventional and modular adapter systems, reflecting Rusan’s long involvement in clip-on mounting solutions. Its modular concept is intended to let one clip-on device serve across multiple rifles or allow different clip-on units to be paired with different riflescopes with less disruption to the overall setup. Alongside those systems, the range also covers dedicated accessories and spare parts for specific night-vision and thermal-device platforms. In practice, the series is defined by precise thread standards, durable metal construction, and compatibility-driven design rather than cosmetic add-ons, making it especially relevant for hunters and shooters who rely on clip-on optics in changing configurations.

About the Rusan Extension Ring for Dedal 552

The Rusan Extension Ring for Dedal 552 is a dedicated mounting accessory for users running a thermal clip-on system built around the Dedal M52x0.75 standard. Its role is straightforward but important: it provides the correct threaded extension interface so compatible components can be joined cleanly, without forcing mismatched parts or compromising the fit of the mounting assembly. In clip-on use, that kind of correct mechanical connection matters because alignment at the adapter level affects how securely the device sits in front of the day optic.

Rusan builds this ring from steel, which suits a part whose job is to provide a stable threaded connection rather than save every possible gram. The result is a component that resists wear at the threads and supports a firm, confidence-inspiring fit during repeated installation and removal. Even so, the ring remains relatively manageable at 50.00 g, so it does not add unnecessary bulk to a front-mounted thermal setup.

Because it is finished in black, the ring integrates neatly with modern clip-on adapters, riflescope housings, and mounting hardware. For the shooter, the main advantage is not visual styling but system coherence: this is a purpose-made part for a specific mounting standard, which makes it a sensible choice when building or maintaining a Dedal-compatible clip-on configuration where fit, thread compatibility, and mechanical stability matter more than universal one-size-fits-all solutions.

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 focus that still defines the brand today. Its product range covers scope mounts, scope rings, Picatinny rails, and firearm tuning components, with strong emphasis on precisely machined mounting hardware.

Rusan is particularly well known for products that connect optics and rifles in a practical, repeatable way, including adapter clamps for night-vision and thermal-imaging devices. The company introduced its clip-on sight adapter clamp in 2009, a milestone that helped shape its reputation in the clip-on optics segment. That background is especially relevant here, because accessories such as extension rings and adapter components depend on the same strengths as a good mount: accurate machining, durable materials, and dependable fit between threaded and clamping interfaces.
