Rusan adapter lever (left thread)

• Left-thread replacement lever: Restores the clamping function of compatible Rusan adapter systems, helping keep a thermal clip-on securely attached and correctly aligned on the riflescope.
• Built for thermal clip-on adapters: Made for Rusan adapter use with clip-on devices, so it supports a practical field setup where repeatable mounting matters.
• Compact spare part: A small component that is easy to keep in a kit bag or workshop, making maintenance or replacement straightforward without carrying a full adapter assembly.
• Black finish: The subdued exterior matches typical hunting and shooting equipment and keeps the accessory visually discreet on the rifle.
• Croatian manufacture: Produced by Rusan in Croatia, reflecting the company’s long focus on precision-made mounting parts and adapter components.

About the Rusan Accessories Series

Rusan Accessories covers the supporting parts that keep the company’s clip-on mounting systems working as intended in the field. The series includes adapters, reduction rings, spare parts and accessory components for attaching night-vision and thermal clip-on devices to riflescopes. Within Rusan’s broader optics-mounting range, these products serve users who need to maintain, adapt or expand an existing setup rather than replace a complete mounting solution.

A defining characteristic of the series is its focus on system compatibility and modular use. Rusan offers both conventional and modular adapter concepts, allowing one clip-on device to be shared across multiple rifles or matched with different riflescopes more efficiently. That makes the accessory range especially relevant for hunters and other users who rely on clip-on thermal or night-vision equipment and want a setup that remains practical over time. Instead of generic hardware, the series is built around purpose-made parts that support correct fit, repeatable positioning and everyday serviceability.

About the Rusan adapter lever (left thread)

The Rusan adapter lever (left thread) is a dedicated spare part for Rusan adapter assemblies used with thermal clip-on devices. Its role is simple but important: it provides the handling point used to tighten or release the adapter, so the clip-on can be mounted securely and removed efficiently when needed. For users who depend on a clip-on setup in changing light or shifting field conditions, a correctly functioning lever is essential to keeping the mounting process quick and controlled.

This version uses a left-hand thread, which means it is intended for the specific Rusan adapter configurations designed around that thread direction. Choosing the correct lever matters because it preserves proper operation of the clamp mechanism and helps avoid unnecessary wear or incorrect fit. In practice, that makes this part most useful as a direct replacement during maintenance, repair or refurbishment of an existing adapter.

Its black finish keeps the appearance consistent with the rest of the mounting system, while the compact format makes it easy to store as a workshop spare or field backup. As a purpose-built Rusan component made in Croatia, it suits users who want to keep an original adapter in service with the correct factory-type part rather than improvise with non-specific hardware.

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. That background in machining and firearms-related engineering remains central to the brand’s identity today.

Rusan specializes in scope mounts, scope rings, Picatinny rails and firearm tuning products, along with adapter systems for night-vision and thermal-imaging devices. The company introduced its clip-on sight adapter clamp in 2009, a product category that became an important part of its international presence. This experience in precision mounting hardware is directly relevant to small functional parts such as adapter levers, where fit, thread compatibility and dependable operation matter as much as the larger assembly itself.
