Rusan Conversion Kit for Modular Adapter, Right Thread

• Converts the clamp to screw operation: This kit replaces the quick-release lever with an Allen screw and bushing, giving the modular adapter a simpler fixed clamping setup that suits users who prefer a tool-operated connection.
• Right-thread configuration: The right-thread layout matches the correct clamp version, so installation remains straightforward and the replacement parts work as intended with compatible Rusan modular adapter clamps.
• Made for MAR modular clamps from 45 mm: Compatibility with Rusan modular adapter clamps starting from 45 mm makes it a practical spare part or conversion option for larger clamp sizes used with clip-on systems.
• Compact field replacement set: By including the required screw and special nut, the kit provides the key parts needed to replace a worn or unwanted quick-release assembly without changing the whole clamp.
• Supports repeatable clip-on setup: In the Rusan modular system, secure clamp positioning helps maintain a stable interface between riflescope and clip-on device, which matters when equipment is removed and reinstalled in regular use.

About the Rusan Accessories Series

Rusan Accessories is the support range built around the company’s adapter systems for night-vision and thermal clip-on devices. The series covers the small but important parts that let users configure, maintain, and adapt a mounting setup to a specific rifle, riflescope, or clip-on combination. It sits alongside Rusan’s conventional and modular adapter lines and is aimed at hunters and other users who need a practical way to move equipment between platforms without replacing an entire mounting system.

A defining idea behind the series is modularity. Rusan developed its adapter ecosystem so that one clip-on device can be used with multiple rifles, or different devices can be paired with different optics, while keeping the mounting process organized and repeatable. Within that system, accessories such as reduction rings, spare parts, and conversion components help tailor the setup to the user’s preferred handling style. Rusan Accessories therefore focuses less on optics and more on the mechanical interface that makes clip-on equipment usable in the field: secure attachment, compatibility across devices, and straightforward serviceability.

About the Rusan Conversion Kit for Modular Adapter, Right Thread

The Rusan Conversion Kit for Modular Adapter, Right Thread is a small but useful accessory for users who want to change how a Rusan MAR modular adapter clamp is operated. Instead of a quick-release lever, this kit converts the clamp to a screw-based arrangement using a new M5 Allen screw and a special nut. In practice, that gives the adapter a more fixed, tool-operated feel, which can suit users who prefer a simple mechanical setup over lever actuation.

This conversion kit is intended for adapter clamps starting from 45 mm, making it relevant for larger clamp sizes in the MAR system. Because it is built specifically for the modular adapter platform, it preserves the basic purpose of the system: creating a stable connection between a riflescope and a thermal or night-vision clip-on device. The benefit is not just replacement of parts, but continued use of an existing clamp in a configuration that better matches the user’s handling preference.

The right-thread version is important because it ensures correct fit with the corresponding clamp design. As a result, the kit works as a proper conversion component rather than a generic hardware substitute. For hunters and clip-on users who rely on the Rusan modular system, this accessory is a practical way to reconfigure or refresh the clamp without replacing the entire adapter assembly.

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. The company entered scope-mount production in 1993 and built its reputation around precisely machined mounting components for sporting and hunting firearms. Its range includes scope mounts, rings, Picatinny rails, and firearm tuning products, with a strong emphasis on fit, repeatability, and mechanical reliability.

Rusan is particularly well known for adapter solutions that connect riflescopes with night-vision and thermal-imaging devices. The company introduced its original clip-on sight adapter clamp in 2009, and that experience shaped the later development of its modular adapter system and related accessories. This background is directly relevant to products like the Rusan Conversion Kit for Modular Adapter, which reflects the company’s focus on practical, field-oriented mounting hardware rather than generic accessories.
