How many clicks is a MOA?

4 clicks on the scope equal 1 MOA. So, if every 4 clicks equals 1 MOA, you will need 5 of those 4 click adjustments, or 20 clicks total.

The good news is that there’s no right or wrong answer here. The choice of a 3 MOA versus 6 MOA red dot sight is entirely up to you and your shooting preference. You may find one works better than the other based on the way you shoot, your eyesight, distance to target or many other factors.
