Rusan adapter lever (right thread - standard)

• Standard right-thread lever: This replacement lever restores the normal clamping action of compatible Rusan adapter clamps, helping keep a thermal clip-on securely positioned on the riflescope.
• Made for adapter maintenance: As a dedicated spare part, it lets worn or damaged hardware be replaced without changing the complete adapter assembly, which is practical for regular field use.
• Compatible with larger clamp sizes: The lever is intended for adapter clamps starting from size 45, making it suitable for the corresponding section of Rusan’s standard clamp system.
• Steel-and-alloy accessory from Rusan: Built by a manufacturer focused on mounts and adapter systems, it matches the fit and function expected for original Rusan clamp components.
• Simple black finish: The black exterior keeps the part visually consistent with the rest of the adapter hardware and avoids a mismatched repair.

About the Rusan Accessories Series

Rusan Accessories covers the supporting parts that keep the company’s clip-on mounting systems working across different riflescope and device combinations. The range includes adapters and reduction rings for night-vision and thermal clip-on devices, along with spare parts and accessory components for both conventional and modular systems. This makes the series relevant not only for first-time installation, but also for maintenance, replacement and system expansion.

A key part of the series is its connection to Rusan’s long-running adapter concept, which the company says entered the global market in 2009. Alongside the established clamp-style products, the line also supports the newer modular approach, whose first prototype was completed in 2020. In practical terms, the series is aimed at hunters and shooters who want to mount a clip-on securely, move one device between rifles, or keep an existing setup serviceable with original replacement parts. The overall design philosophy is straightforward: precise fit, compatibility within the Rusan ecosystem, and hardware that supports repeatable attachment of thermal and night-vision equipment.

About the Rusan adapter lever (right thread - standard)

The Rusan adapter lever (right thread - standard) is a small but important spare part for maintaining a working clip-on mounting setup. It is intended for Rusan adapter clamps starting from size 45, where the lever forms part of the clamp mechanism used to secure a thermal clip-on adapter to the riflescope. When the original lever is worn, damaged or missing, replacing just this component is often the most practical way to return the adapter to proper use without replacing the complete clamp.

Its right-thread standard configuration matters because adapter hardware must match the original thread direction and clamp design to function correctly. In use, that means the lever can restore the expected tightening action and handling feel of the adapter, helping the user lock the assembly in place with the correct mechanical movement. For clip-on systems, this is important because stable attachment supports consistent positioning of the thermal device in front of the day optic.

Finished in black and made as an original Rusan accessory, this lever suits users who prefer to keep their mounting system serviceable with factory-matched parts. It is a straightforward component, but one that plays a direct role in the reliability and usability of a thermal clip-on adapter in the field.

About Rusan

Rusan-Mikron is a Croatian manufacturer based in Marija Bistrica, with roots in the Rusan family’s metalworking business dating to 1983. Željko Rusan opened a gunsmith shop in 1986, and the company began producing scope mounts in 1993. That background in machining and firearms-related hardware remains central to the brand’s identity today.

Rusan is known for manufacturing scope mounts, scope rings, Picatinny rails and firearm tuning products, as well as adapter systems for night-vision and thermal-imaging devices. The company introduced its clip-on sight adapter clamp in 2009, and that product family remains one of its most recognized areas of expertise. In this category, Rusan’s reputation is built on practical engineering: precise fit, repeatable mounting and a broad range of parts that support both complete installations and long-term maintenance.
