They are made of robust, corrosion-resistant aluminum, are lightweight, precisely fitting, and enable quick installation without tools – ideal for hunting use under changing conditions.

Compatible devices / notes

The Rusan Q-R adapter ensures that a clip-on device can be securely and quickly attached to a daylight riflescope – depending on the thread type, the appropriate device is mounted on it.

Important: The selection of the correct adapter is based on the device-side thread – not on the diameter of the riflescope objective.
