Rusan Modular QR Adapter for Guide

• Quick-release modular interface: The modular QR design lets a compatible Guide thermal clip-on be attached and removed quickly, which helps when one device is shared between riflescopes or moved between setups in the field.
• Guide M33.5x0.75 compatibility: Built for the Guide mounting standard, this adapter provides the correct interface for secure connection to compatible clip-on devices without improvised fitting solutions.
• Wide riflescope fit range: Compatibility with eyepiece-side diameters from 30 mm up to 67 mm makes the system practical for users running different scopes and objective housings.
• Steel construction: The steel body gives the adapter the rigidity needed for repeatable positioning, which matters when a clip-on must return to the same alignment after removal and reinstallation.
• Purpose-built for thermal clip-ons: As a dedicated adapter for thermal clip-on use, it is designed around stable mounting and straightforward handling rather than serving as a generic ring or spacer.

About the Rusan Accessories Series

Rusan Accessories is the part of the Rusan range focused on the practical hardware that connects optics, riflescopes, and clip-on devices into a usable field setup. Within this family, a major emphasis is placed on adapters and reduction components for night-vision and thermal clip-on devices, giving users a way to match one device to different riflescopes or even multiple rifles. That flexibility is central to the series: instead of treating every optic and clip-on combination as a fixed pairing, the system is built to make interchange easier and more repeatable.

The series includes both conventional and modular adapter systems. The modular concept was developed to improve speed and convenience when moving a clip-on between platforms, while still keeping the secure mechanical fit needed for hunting optics and observation use. In practical terms, that makes the series well suited to users who want to standardize around one thermal or night-vision device and adapt it to several riflescope diameters. Alongside these adapters, the broader accessories line also includes related mounting components and spare parts, making Rusan Accessories a functional support range rather than a collection of isolated parts.

About the Rusan Modular QR Adapter for Guide

The Rusan Modular QR Adapter for Guide is a dedicated mounting component for users who run a Guide-standard thermal clip-on with M33.5x0.75 thread compatibility and want a faster, more adaptable connection to a riflescope. Its role is straightforward but important: it forms the interface between the clip-on device and the scope-side adapter system, allowing the thermal unit to be mounted in a way that supports repeatable positioning and practical day-to-night transitions.

What makes this model especially useful is its place within the Rusan modular quick-release system. A modular setup is valuable when one thermal clip-on is used across more than one riflescope, or when a shooter wants to keep scope-side components matched to different optic diameters and move only the device-side section as needed. That reduces setup time and makes the overall system easier to manage in the field. Because this adapter is made from steel, it prioritizes mechanical stability and durability, both of which are important when supporting a clip-on in front of a day optic.

Compatibility is another strong point. This version is intended for Guide mounting geometry and works with a broad range of rear adapter diameters, including 30 mm, 34 mm, 36 mm, 48 mm, 50 mm, 56 mm, 62 mm, 65 mm, and up to 67 mm. That broad fit range makes it a practical choice for users with several riflescopes in rotation. Finished in black, it matches typical hunting and tactical optics setups while keeping the focus on secure function rather than unnecessary bulk.

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 progression from metalworking to gunsmithing and then to dedicated optics-mounting products explains why Rusan is closely associated with precise mechanical components for sporting and hunting firearms.

Today, the company produces scope mounts, scope rings, Picatinny rails, and firearm tuning products, along with adapters for night-vision and thermal-imaging devices. Rusan introduced its original clip-on sight adapter clamp in 2009, a milestone that remains particularly relevant to this product category. That long focus on mounting solutions is reflected in the company’s adapter systems, which are designed around secure fit, repeatable alignment, and compatibility with a wide range of riflescopes and clip-on devices.
