How to adjust according to the text on the optical scope adjustment knob
Sep 15, 2018

The high-quality gun sights are equipped with anti-vibration adjustment knobs, and each time you adjust one, there will be one sound. English will be indicated on each adjustment plate. For example, the label is 1CLICK O 1/4"YD. It means that each adjustment of a grid (ie, a volume of sound) 100 yards of movement is 1/4 inch. Inches, the conversion between code and cm, m For details, please read it yourself. Of course, there are still many gun sights marked as 1CLICK O 1/2"YD or 1CLICK O 1/8"YD. Their meaning is to adjust one grid (ie, one sound volume) 100 yards. The amount of movement is 1/2 inch or 1/8 inch. The smaller the number of inches, the higher the distance accuracy of the scope, but usually the close distance is not much different.
