Rusan Modular Adapter for Night Pearl

• Modular clip-on interface: This adapter links a Night Pearl thermal clip-on with the Rusan modular system, making it easier to move one device between compatible riflescopes without changing the clip-on-side connection.
• M43x0.75 Night Pearl thread: The dedicated front interface matches the Night Pearl mounting standard, which helps maintain a secure, correctly matched fit for dependable alignment in field use.
• Broad riflescope compatibility: With rear-side compatibility across many outer diameters from 30 mm up to 67 mm, the system supports use with a wide range of daytime optics when paired with the correct modular clamp section.
• Steel construction: The steel body gives the adapter the rigidity needed for repeatable mounting, helping the clip-on stay stable under regular handling and recoil.
• Black protective finish: The subdued black finish keeps reflections low and suits hunting or professional rifle setups where a discreet appearance and practical durability matter.

About the Rusan Accessories Series

Rusan Accessories is the company’s broad family of mounting and interface components for riflescopes, night-vision devices, and thermal clip-on systems. Within this range, the modular adapter products are built around a simple idea: let one clip-on device work across multiple rifles or let different clip-on units be matched with different optics without relying on a separate dedicated mount for every combination. That makes the series especially relevant for hunters and other users who want a more flexible way to configure their equipment.

The series includes adapters, reduction rings, and related parts for specific night-vision and thermal-device platforms, alongside Rusan’s wider mounting products such as rails and rings. A key distinction in the line is that Rusan offers both conventional and modular adapter systems, giving users a choice between a more traditional setup and a system designed around interchangeability. The modular concept was developed to improve practicality in everyday use, and the finalized design has remained in production after the first prototype was completed in 2020. In practical terms, the series is defined by compatibility, repeatable mounting, and system flexibility rather than by optical features, because its role is to connect clip-on technology to the riflescope securely and consistently.

About the Rusan Modular Adapter for Night Pearl

The Rusan Modular Adapter for Night Pearl is a purpose-built connector for integrating a Night Pearl mounting standard (M43x0.75) thermal clip-on into the Rusan modular adapter system. Its job is straightforward but important: it creates the dedicated device-side interface that allows the clip-on to be paired with the appropriate rear adapter section for the riflescope. For users running thermal clip-on equipment on more than one rifle, that modular approach is more practical than treating every setup as a separate one-piece mount.

This model is especially useful because it combines a device-specific front thread with broad downstream compatibility. Once connected into the modular system, it can be used with rear adapter sizes covering many common riflescope objective housings, including 48 mm, 50 mm, 56 mm, 62 mm, 65 mm, and 67 mm among others. That gives the adapter real value for shooters who change optics platforms over time or maintain several rifles with different daytime scopes. Instead of replacing the entire interface, the modular concept allows the Night Pearl side to remain constant while the riflescope-side component is matched to the optic.

The adapter body is made from steel, which suits a mounting component where stiffness and secure engagement matter more than low weight alone. In use, that solid construction helps support stable positioning of the clip-on and contributes to repeatable alignment when the system is assembled correctly. Finished in black, the adapter also integrates neatly with modern hunting optics and thermal equipment without adding unnecessary visual bulk to the rifle.

About Rusan

Rusan is a Croatian manufacturer based in Marija Bistrica, where the company operates as Rusan-Mikron. The family metalworking business dates to 1983, and Željko Rusan opened a gunsmith shop in 1986. Scope-mount production followed in 1993, establishing the company’s long-term focus on precision mounting solutions for sporting and shooting optics.

Today, Rusan is known for manufacturing scope mounts, scope rings, Picatinny rails, and firearm tuning products, with a particularly strong reputation in adapters for night-vision and thermal-imaging devices. The company introduced its original clip-on sight adapter clamp in 2009, a milestone that helped define its place in the clip-on mounting segment. That background is directly relevant here: Rusan’s expertise lies not in optics themselves, but in the mechanical interface between rifle, riflescope, and add-on sighting equipment, where precise machining and repeatable fit are essential.
