Rusan Two-Piece Adapter for Guide

• Two-piece clip-on interface: The two-piece design lets the adapter stay matched to the riflescope while providing a secure connection for a Guide thermal clip-on, making setup more practical when the device is moved between optics.
• Guide M33.5x0.75 compatibility: Built for the Guide mounting standard, this adapter gives a correct mechanical fit for compatible thermal clip-on units and helps maintain stable alignment in front of the day scope.
• Wide scope-diameter coverage: Compatibility with many riflescope outer diameters, from 30 mm up to 65 mm in listed sizes, makes it easier to match the adapter to different hunting optics without changing the clip-on system.
• Steel construction: A steel body provides the rigidity needed for repeatable mounting and dependable long-term use on rifles that see regular field handling.
• Front clip-on mounting solution: By positioning the thermal device in front of the riflescope, the adapter preserves the familiar sight picture and shooting position of the daytime optic.

About the Rusan Accessories Series

Rusan Accessories is the part of the Rusan range focused on the practical connection between riflescopes and add-on aiming equipment. The series includes adapters and reduction rings for night-vision and thermal clip-on devices, alongside related mounting components that help users build a system around a specific optic and device combination. Within the wider Rusan lineup, this family sits between the company’s conventional scope-mounting products and its more specialized clip-on solutions.

A defining characteristic of the series is its emphasis on system compatibility. Rusan offers both conventional and modular adapter systems, allowing users to choose between a straightforward dedicated setup and a more flexible arrangement for multiple rifles or multiple clip-on devices. That makes the series relevant to hunters and other shooters who want a stable front-mounted thermal or night-vision solution without changing the handling of their daytime riflescope. Across the range, the design philosophy is mechanical rather than electronic: precise fit, durable materials, and repeatable attachment are the priorities, because those are the factors that matter most when a clip-on device has to sit squarely in front of the optic.

About the Rusan Two-Piece Adapter for Guide

The Rusan Two-Piece Adapter for Guide is a dedicated mounting solution for fitting a Guide-standard thermal clip-on with M33.5x0.75 in front of a riflescope. Its role is straightforward but important: it creates the mechanical link between the clip-on device and the day optic, so the thermal unit sits concentrically and securely in front of the scope. That front-mounted arrangement is especially useful for hunters who want to keep the rifle, cheek weld and daytime optic unchanged while adding thermal capability only when conditions require it.

The adapter’s two-piece construction is what sets it apart from a simple one-piece ring. In practical use, a two-part system can make handling more convenient when matching the clip-on to the riflescope and maintaining a consistent setup. The adapter is also designed around broad scope-body compatibility, covering listed rear diameters from 30 mm to 65 mm across multiple size options. That makes it suitable for a wide range of hunting optics, from more compact scopes to larger objective models that still need a correctly matched outer-diameter interface.

Its steel construction supports the kind of rigidity expected from a clip-on mount, where stability matters more than saving a small amount of weight. The black finish keeps the appearance discreet and consistent with most riflescope and thermal-device housings. As an accessory for thermal clip-ons rather than a standalone optic, the value of this adapter lies in fit, alignment and durability: it is built to provide a dependable connection between a compatible Guide clip-on and the riflescope it is mounted in front of.

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 is important because it explains why Rusan is closely associated with the mechanical side of sporting optics: mounts, rings, rails and related firearm components built around precise machining and practical field use.

Today, Rusan is known for products such as scope mounts, scope rings, Picatinny rails and adapters for night-vision and thermal-imaging devices. The company introduced its original clip-on sight adapter clamp in 2009, a milestone that helped establish its reputation in the clip-on mounting segment. This long focus on adapter systems and firearms mounting hardware makes Rusan particularly relevant in categories where secure fit and repeatable alignment are central to performance.
