Rusan Two-Piece Adapter for Armasight

• Two-piece clip-on interface: The split adapter design joins an Armasight Mounting Standard (M39x1.0) thermal clip-on to a riflescope with a secure mechanical connection that supports stable alignment in field use.
• Broad eyepiece-size compatibility: With rear compatibility from 30 mm to 65 mm, this adapter format suits many riflescope objective housings and helps match an Armasight clip-on to different optics.
• Steel construction: The steel body gives the adapter the rigidity needed for repeatable mounting and long service life on hunting optics and thermal clip-on setups.
• Purpose-built for thermal clip-ons: Designed specifically for thermal clip-on use, it provides a practical way to mount front add-on devices without changing the basic handling of the day scope.
• Compact, straightforward mounting solution: As a dedicated adapter for the Armasight interface, it keeps the connection simple and application-focused for users who want a direct fit rather than a universal workaround.

About the Rusan Accessories Series

Rusan Accessories is the part of the Rusan-Mikron range focused on the hardware that makes clip-on systems practical in the field. The series includes adapters and reduction rings for mounting night-vision and thermal clip-on devices to riflescopes, giving hunters and shooting users a way to build a setup around the exact device and optic they already use. A key characteristic of the series is that it covers both conventional and modular adapter systems, so users can choose between a dedicated fixed-format solution and a more flexible system for sharing one clip-on across multiple rifles.

Within the wider Rusan lineup, these accessories sit alongside the company’s mounts, rings, and rails, but they are aimed specifically at the demands of clip-on thermal imaging and night-vision use. The design philosophy is practical rather than decorative: secure fit, precise machining, and compatibility across many riflescope dimensions. The series also includes model-specific parts, adapter accessories, and spare components, which makes it useful not only for first installation but also for maintaining or expanding an existing clip-on setup over time.

About the Rusan Two-Piece Adapter for Armasight

The Rusan Two-Piece Adapter for Armasight is a dedicated mounting solution for pairing an Armasight M39x1.0 thermal clip-on interface with a day optic. Its role is straightforward but important: it creates the mechanical link between the clip-on unit and the riflescope so the thermal device can be used in front of the optic in a controlled, repeatable way. For clip-on systems, the quality of that connection matters because poor fit can affect alignment, handling, and confidence in the setup. A steel adapter addresses that need with the stiffness and wear resistance expected from a part that is repeatedly mounted and removed.

This model is especially useful because it supports a wide range of rear diameters, from 30 mm up to 65 mm, including intermediate sizes such as 56 mm, 57.5 mm, 58.4 mm, 59 mm, and 62 mm. That broad compatibility makes it easier to match an Armasight clip-on to many different riflescope housings without changing the clip-on standard at the front. The two-piece construction also reflects the practical needs of clip-on users: one side is dedicated to the Armasight mounting standard, while the other is selected to suit the scope dimension. In use, that means a more purpose-built fit than a generic adapter approach, which is particularly relevant for hunting optics where secure attachment and consistent positioning are more important than unnecessary complexity.

About Rusan

Rusan-Mikron is a Croatian manufacturer based in Marija Bistrica, and the company’s background in metalworking goes back to 1983. The business developed from gunsmithing and precision metalwork into a specialist producer of scope mounts, rings, Picatinny rails, and firearm-related components. Rusan began producing scope mounts in 1993, building the machining experience that later supported its expansion into clip-on adapter systems.

For users of thermal and night-vision equipment, Rusan is particularly known for its adapter clamps and connection systems for attaching clip-on devices to riflescopes. The company introduced its original clip-on sight adapter clamp in 2009, and that product category remains a core part of its offering. Today, Rusan’s reputation in this segment rests on practical engineering, broad compatibility across rifle and optic platforms, and durable steel and alloy mounting components made for regular field use.
