Here is a video for how we check the Rotation problem when we received the client's feedback.


1. Remove the zero knob.

2. Install the zero knob.

3. Put it on the collimator ( which set on 100 yards ) and change the magnification. No need any adjust, the reticle is on the center.


Should you have any queries please feel free to let us know. Thank you.


Best regards


Tracy
