Rusan Reducing Ring for ATN PS28 (M49x0.75)

• M52x0.75 to M49x0.75 thread reduction: lets an ATN PS28 interface with a compatible Rusan Q-R adapter, so a clip-on thermal setup can be matched to the riflescope adapter system already on the rifle.
• Built for conventional Rusan adapters: this ring is made to work with the Rusan conventional universal adapter M52, giving a practical way to complete a clip-on mounting solution instead of replacing the whole adapter system.
• Steel construction: the steel body adds thread strength and wear resistance, which matters on parts that are repeatedly installed, removed, and tightened during field use.
• Counter nut included: the supplied counter nut helps secure the ring in the correct position on the device, supporting a more stable and repeatable fit.
• Wrench included: the included tool makes installation simpler and helps achieve proper tightening without improvising with unsuitable tools.

About the Rusan Accessories Series

Rusan Accessories is the part of the Rusan range focused on the small but essential components that make clip-on systems practical in real use. The series covers adapters and reduction rings for night-vision and thermal clip-on devices, alongside related mounting parts that let different devices and riflescopes work together within the same setup. A key idea behind the range is flexibility: one clip-on can be shared across multiple rifles, or different clip-on devices can be matched to different optics without rebuilding the entire mounting arrangement.

Within the wider Rusan lineup, this series sits alongside the company’s scope mounts, mounting rings, and Picatinny and Weaver rails, but it is especially relevant to hunters and shooters using front-mounted thermal or night-vision equipment. The range includes both conventional and modular adapter systems, so users can choose between a straightforward dedicated arrangement and a more configurable system. That makes the series well suited to clip-on use, where thread standards, device-specific interfaces, and repeatable alignment matter just as much as the optic itself.

About the Rusan Reducing Ring for ATN PS28 (M49x0.75)

The Rusan Reducing Ring for ATN PS28 (M49x0.75) is a device-specific adapter component for building a proper clip-on mounting solution around the ATN PS28 thermal clip-on. Its job is straightforward but important: it converts from M52x0.75 on the adapter-clamp side to M49x0.75 on the clip-on side, allowing the PS28 to interface with Rusan’s conventional adapter system. In practice, that means the ring acts as the connection point between the clip-on device and the larger adapter assembly fitted to the day scope.

Because this is only a thread reducing ring, it is intended to be combined with a Rusan Q-R adapter in the appropriate size for the riflescope. That approach is useful for shooters who want a clean, device-specific interface without giving up the convenience of a quick-detach clip-on setup. Rather than forcing a one-piece solution, the ring keeps the system modular where it matters most: at the junction between the thermal device and the riflescope adapter.

The ring is made from steel, which is a sensible choice for a threaded component that must resist wear from repeated fitting and removal. At 50.00 g, it adds little bulk to the overall setup. The included counter nut and wrench support correct installation and positioning, helping the adapter assembly stay secure and practical for regular field use on hunting optics and other clip-on thermal applications.

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. The company moved into scope-mount production in 1993, building on earlier gunsmithing experience and developing a strong focus on precision-made mounting components for sporting and shooting use.

Today, Rusan is known for scope mounts, scope rings, Picatinny rails, and firearm tuning products, as well as adapter systems for night-vision and thermal devices. Its clip-on adapter clamp, introduced in 2009, is especially relevant in this category because it helped establish the company’s reputation for practical, repeatable mounting solutions. That background makes Rusan a natural fit for products such as reduction rings and clip-on adapters, where thread accuracy, material quality, and dependable mechanical fit are more important than cosmetic design.
