Rusan 3x Magnification Eyepiece with Modular Connector

• 3x magnification eyepiece: turns a compatible thermal clip-on into a handheld observation device with more image scale, making it easier to assess detail without mounting the unit behind a day scope.
• Modular connector interface: attaches through the Rusan modular system for a secure, repeatable fit that simplifies switching between clip-on and viewing configurations.
• Built for thermal clip-ons: gives clip-on users a practical way to use the same device for scanning and identification, reducing the need for a separate monocular.
• Compact accessory format: adds viewing capability without the bulk of a dedicated optical housing, helping keep field equipment simpler and easier to carry.
• Croatian-made Rusan construction: comes from a manufacturer known for metalworking and mounting solutions, which suits users who value robust, purpose-built accessories.

About the Rusan Modular Series

Rusan modular accessories are designed around a simple idea: one thermal or night-vision device can serve in more than one role when the connection system is consistent and secure. Within the company’s lineup, the modular connector system supports clip-on use while also allowing selected accessories such as eyepieces, covers and adapters to be fitted as needed. This makes the series especially relevant for users who want to move between rifle-mounted and handheld observation roles without replacing the core device.

The series is aimed at hunters and other field users who rely on clip-on thermal and night-vision equipment and want a practical way to adapt it to changing tasks. Rather than focusing on electronics or display technology, the modular range centres on mechanical compatibility, repeatable attachment and straightforward handling in the field. That design approach suits users who already have a clip-on unit and need dependable accessory integration, whether for transport, protection or converting the device into a more convenient observation tool.

About the Rusan 3x Magnification Eyepiece with Modular Connector

The Rusan 3x Magnification Eyepiece with Modular Connector is a dedicated accessory for thermal clip-on devices that adds a practical handheld viewing function. Instead of limiting the clip-on to rifle use, this eyepiece lets the same device work as a more observation-focused optic. The 3x magnification gives the image more usable scale, which helps when checking heat signatures, reading terrain features or making a more careful identification before moving into position.

Its main advantage is the integrated modular connector. Because it is built for the Rusan modular system, the eyepiece is intended to fit into an established accessory setup rather than acting as a generic add-on. In practice, that means a cleaner conversion between roles and a more secure connection than improvised solutions. For users who already depend on a clip-on thermal in the field, this can reduce the amount of separate equipment they need to carry.

The format also makes sense ergonomically. A clip-on paired with a magnification eyepiece becomes easier to use for short periods of scanning or target confirmation away from the rifle. The result is a focused accessory that does not try to replace a dedicated monocular, but instead gives a compatible thermal clip-on greater versatility and a more efficient role in hunting optics equipment.

About Rusan

Rusan comes from a family metalworking business whose history dates to 1983. The company’s development in firearms-related products followed the opening of a gunsmith shop by Željko Rusan in 1986, and it began producing scope mounts in 1993. This background helps explain why the brand is closely associated with practical mounting solutions and mechanical accessories rather than electronic optics.

Based in Marija Bistrica, Croatia as Rusan-Mikron, the company manufactures scope mounts, scope rings, Picatinny rails and firearm tuning products. It is also well known for adapter clamps for clip-on sights and adapters for night-vision and thermal-imaging devices. Rusan introduced its clip-on sight adapter clamp in 2009, and that experience remains directly relevant to accessories such as modular connectors and eyepieces for clip-on systems.
