I recently I purchase my first AR (Colt 6920). I'm tying to understand how to zero my sights, what really confuse me is the front post adjustment. I found 2 links that says the opposite things . The first say: "Before firing the second group, I brought the front sight down two clicks, thus raising the point of aim. Here are the results" usmc25mar-15zero - Jimmy Hots This guy first group was shooting low so he brought down the front post. The 2nd link states: To raise the next shot group, rotate the front sight post in the direction marked UP (clockwise) To lower the next shot group, rotate the front sight post in the direction marked DOWN (counter-clockwise) To move the next shot group left, turn windage knob counterclockwise To move the next shot group right, turn the windage knob clockwise :: Guides Now I'm confuse, I would think if I'm shooting low I would lower the front post? Every manual I've read say to bring the post to the direction you want the next group, which to me doesn't make sense.
