Rusan Adapter ARM52-30

Rusan adapters are used to connect a daylight optic to a night vision or thermal imaging attachment with M52x0.75 thread. Many attachments are already equipped with the appropriate thread. However, due to the various thread adapters or reducing rings, the Rusan ARM-52 adapter can also be used beyond this and is compatible with almost all common night vision optics.

 

To determine the appropriate diameter for mounting the Rusan adapter, the outer diameter of the optics must be measured with a tolerance of 0.5 millimeters. Ideally, use a caliper gauge to do this.
