Rusan Q-R adapter for devices with thread M52x0.75 - Ø viewer adapter
Rusan adapters are made to mount the forzet scope on the rifle scope. The Rusan Q-R mounts were once made for military applications, but are now also made for the consumer market. The Rusan Adapters are really the standard in the market though.
The inside is covered with a blue coating, so the viewer does not get damaged and provides extra grip. Also on the new line is the coating on the front side of the viewer, so there is no audible click / tap measure when the Rusan adapter is slid over the rifle scope.
The Rusan Q-R adapter is the standard ring that fits on a lot of front mounted scopes, there are also many adapters available to fit this ring on salle possible front mounted scopes. The Rusan adapter has a small thickening with two screw holes, here it is possible to mount a picatinny rail.
