- Leica Calonox Sight to Rusan Riflescope
- Throw-Lever tensioning sleeve
The LEICA ARM52-58 Rusan Sight Adapter allows you to join a Leica Calonox Sight with a Rusan scope. It's a throw-lever tensioning sleeve that threads onto the eyepiece end of the Calonox and slides over the objective lens housing.
The Rusan Adapter is a simple way of attaching a thermal clip-on device to your day scope's objective. Simply slip it over the front lens of your scope and move the lever to the "clamp closed" position.
The adapter slips over approximately 1.4" of your objective lens so there is lots of clamping surface area for a great hold. The inside of the adapter is lined with a special film to provide for extra gripping power and assures a scratch free attachment.
