Rusan Quick-Release Objective adapter for Nightvision or Thermal devices with thread M52x0.75.
Rusan quick-release adapter
Use this device to connect your scope to your favorite addons with an M52x0.75 thread (or with the correct reducing ring) such as night vision or thermals. Built in Europe to the highest standards to ensure reliability and robustness backed by a 30 year warranty.
Simply measure the outside diameter of the objective bell and find the correct size for your scope. If we don’t have one in stock that matches your size go to our CONTACT US page, leave your name and email and we can order one for you.
Please Note: It is the outside diameter of your scope lens housing that determines the adapter size needed, not your lens size.
For example, Leica scopes with 44mm objective lenses have an external housing diameter of 52mm. For a Leica 44mm scope you would need Rusan Adapter Model: ARM52-52 to attach the Leica Calonox sight. It is the last two numbers in the product SKU that indicate adapter size.
