Hi I am new to AIMPOINT world. I have shot ACOG'S before and know how to zero them. I went to Aimpoints Web-site and they said to Zero Aimpoint you aim red-dot at center of target,take a shot. If your shot is to the right of the Bulls eye. You steady rifle again and look through the AIMpoint and turn knobs to move the dot to the Bullet hole or POI. With my Acog if you are shooting to the right of POA then you move your windage to the left you dont have to be looking through the sight to do this. why is this with the aimpoint? please advise
