Rusan Modular Adapter for GT-Nano

• Modular GT-Nano interface: This adapter connects a GT-Nano thermal clip-on with the M36x1 mounting standard to a riflescope-based modular setup, making it easier to move the device between suitable optics without changing the clip-on itself.
• Broad rear-diameter compatibility: Support for a wide range of riflescope outer diameters, from 30 mm up to 67 mm, gives the system flexibility across different daytime optics and simplifies matching the clip-on to existing equipment.
• Steel construction: The steel body provides the rigidity needed for a mounting component, helping the adapter maintain secure alignment during repeated fitting and removal in field use.
• Purpose-built for thermal clip-ons: Designed specifically for thermal clip-on applications, the adapter forms part of a practical front-mounting solution that keeps the daytime riflescope in place while adding thermal capability.
• Modular system concept: As part of the Rusan Accessories range, this adapter supports a modular approach in which one clip-on can be paired with different riflescopes by using the appropriate rear interface components.

About the Rusan Accessories Series

Rusan Accessories is the part of the Rusan-Mikron range dedicated to the practical integration of optics and electro-optics. Within this family, the focus is on adapters and reduction rings for attaching night-vision and thermal clip-on devices to riflescopes, alongside related mounting components. The series sits naturally beside the company’s scope mounts, rings, and rails, but it is aimed more specifically at users who need to combine a daytime optic with a front-mounted observation or aiming aid.

A defining characteristic of the series is that it includes both conventional and modular adapter systems. The modular concept is especially useful for hunters and shooters who want to use one clip-on device on multiple rifles, or who need a more flexible way to pair different clip-on units with different riflescopes. Rusan introduced its original clip-on adapter to the global market in 2009, and the first modular-adapter prototype followed in 2020. That development path shows a clear design philosophy: durable metal construction, repeatable fit, and a system-based approach that makes thermal and night-vision equipment easier to integrate into real field use.

About the Rusan Modular Adapter for GT-Nano

The Rusan Modular Adapter for GT-Nano is a dedicated interface component for fitting a GT-Nano thermal clip-on into Rusan’s modular adapter ecosystem. Its front compatibility is built around the M36x1 mounting standard used by the device, while the rear side is intended to work with a broad selection of riflescope diameters. In practice, that makes this adapter a useful choice for users who want to build a repeatable clip-on setup around an existing daytime optic rather than commit one thermal unit to only one riflescope.

The main advantage of this model is not complexity but fit. By matching the GT-Nano standard on the device side and offering compatibility with many common outer diameters on the riflescope side, it supports a cleaner and more adaptable mounting solution for thermal hunting optics. This is particularly helpful when equipment changes over time, such as moving a clip-on between rifles or replacing a daytime scope without abandoning the rest of the mounting system.

Steel construction is an important part of the design. For an adapter, material choice matters because the component must resist wear from repeated installation and maintain stable positioning between the clip-on and the host optic. The black finish keeps the appearance discreet and consistent with typical riflescope and thermal-device housings. Overall, this model is best understood as a purpose-built mechanical link: simple in concept, but central to building a stable and flexible GT-Nano clip-on setup.

About Rusan

Rusan is a Croatian manufacturer 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. Based in Marija Bistrica, Croatia, Rusan-Mikron has built its reputation around precision-made mounting solutions for sporting and hunting firearms.

The company’s range includes scope mounts, scope rings, Picatinny rails, and firearm tuning products, along with adapter systems for night-vision and thermal-imaging devices. Rusan introduced its clip-on sight adapter clamp in 2009, a milestone that established the brand strongly in the field of clip-on integration. That background is especially relevant here, because products such as the GT-Nano adapter reflect the company’s long-standing focus on practical mechanical interfaces that connect optics securely and repeatably.
