Rusan Modular QR Adapter for GT-Nano

• Modular quick-release design: lets a GT-Nano clip-on move between compatible riflescope setups faster than a fixed adapter, which is useful when one thermal device is shared across more than one rifle.
• M36x1 GT-Nano interface: matches the GT-Nano mounting standard for a secure mechanical connection, helping maintain consistent alignment between the clip-on and the day optic.
• Broad riflescope compatibility: works with a wide range of rear diameters, making it easier to match the adapter to many common objective housings without changing the clip-on device itself.
• Steel construction: gives the adapter the rigidity needed for repeatable mounting and removal, while also standing up well to regular field handling.
• Modular system concept: forms part of Rusan’s interchangeable adapter platform, so the mounting setup can be configured around different riflescopes and clip-on combinations instead of being limited to one fixed arrangement.

About the Rusan Accessories Series

Rusan Accessories is the part of the Rusan range built around practical integration of optics and clip-on devices. The series includes adapters and reduction rings for night-vision and thermal clip-ons, alongside related mounting components that help connect a device to different riflescope formats. Within the wider Rusan lineup of mounts, rings and rails, this family focuses on the interface between the day optic and the clip-on unit.

A key distinction in the series is the availability of both conventional and modular adapter systems. The conventional designs suit users who want a direct, dedicated setup, while the modular system is intended for shooters who need more flexibility in the field. That modular approach allows one clip-on device to be used with multiple rifles or different clip-on units to be paired with different riflescopes more efficiently. The first modular-adapter prototype was completed in 2020, and the finalized design remains in production. Across the series, the emphasis is on precise fit, repeatable positioning and a mounting layout that supports thermal and night-vision use without making the rifle unnecessarily complicated.

About the Rusan Modular QR Adapter for GT-Nano

The Rusan Modular QR Adapter for GT-Nano is a purpose-built mounting solution for users who want to fit a GT-Nano thermal clip-on to a compatible day optic while keeping the setup adaptable. Its defining feature is the combination of the GT-Nano M36x1 mounting standard at the front and a modular rear interface sized for a broad range of riflescope objective diameters. In practice, that makes the adapter especially useful for hunters and other thermal users who may run the same clip-on on more than one rifle or swap between optics with different outer dimensions.

The quick-release concept matters because a clip-on system is only convenient when it can be attached and removed without turning every changeover into a workshop job. Here, the modular layout is designed to make handling faster while still prioritizing a stable connection between the thermal unit and the riflescope. That stability is important for maintaining consistent visual alignment and for reducing unwanted movement at the mounting point.

Steel construction gives the adapter the strength and stiffness expected from a component that sits between two critical optical elements. The black finish keeps the appearance discreet and matches typical hunting-optics and tactical-optics setups. Because this model is dedicated to the GT-Nano platform, it is best understood not as a generic ring clamp but as a system component that helps turn a compact thermal clip-on into a repeatable, field-ready sighting arrangement.

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. 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 still defines the brand’s product focus today.

Rusan specializes in scope mounts, scope rings, Picatinny rails and adapter systems, along with related firearm-tuning products. In the clip-on category, the company is particularly known for adapter clamps for night-vision and thermal-imaging devices. Rusan introduced its original clip-on sight adapter clamp in 2009, establishing a product line that later expanded into modular systems for more flexible rifle and optic combinations. This long focus on mounting hardware is what makes the brand especially relevant in products such as clip-on adapters, where fit, repeatability and machining quality matter as much as the optical device itself.
