I have a side rail mounted scope on my vepr. I am wondering how do you adjust the tension on the leaver that holds it in place. The instructions I got with the scope is in Chinese and I can not read nor understand Chinese.

This uses the castle nut for tension.

You push down on the clamp itself (push it towards the body of the optic) and slightly hold the castle nut. Rotate the nut up or down to adjust how far the clamp extends when the lever is locked. There is a center cutout on the Vepr rail and the clamp pushes into the center cutout. Adjust the nut too far and the clamp prevents it from sliding on the rail, too little and it won't catch the center cut out.

RS Regulate side mounts use basically the same system
