How to adjust ICS AK Low/Mid Cap – ICS ARK

How to adjust the ICS AK low/mid cap from 50 to 30 bbs, or the other way around.

A questions that I got and it was not very clear to actually change the internal capacity. You can find that you need to turn left or right, but nowhere is stated that you also need to push it before turning. So I made a small video to show how it works.
