The Rusan adapter for HIKMICRO Thunder devices is a one piece adapter for use on HIKMICRO Thunder and Cheetah “C” devices. The new HIKMICRO Thunder one piece design eliminates the need for a Reduction Ring (HIKMICRO Clip On Adapter is still required).

The adapter features a silent clip-on whereas the adapter has internal rubber-based tape that enables the hunter to mount the clip on silently.

Rusan adapters have been built with accuracy in mind. Other adapters use inlets which overtime will cause inaccuracies and loose zero.

The Rusan adapters are designed to not require inlets. The adapters only have a 0.02mm adjustment, therefore, it is especially important to measure the correct outside diameter of your day-scope in order to purchase the correct adapter for your specific scope.
