Howdy everyone. Got a question here regarding the sights on my AR. I have this rear sight, A.R.M.S., Inc.[hsh]40L that came on my slightly used RRA 16" upper. And the attached picture is the result at 50 yards. The high group is me using the top notch of the rear flip up, with the horizontal parts of both the rear and front sight even, and the center of the target right on top of the center front sight post (pumpkin on a fence post). The low group is the center hole of the rear flip up, with the front post just poking up, and the center of the target dead center in the aperture of the rear sight. These results were consistent through 3 different targets, except I was more accurate horizontally/windage wise on the 2 others. For the most part, I am still somewhat of a novice. However, I did attend 1 day of Appleseed a few months ago, so I am at least somewhat familiar with the proper motions and human mechanics involved, I'm just doubting my use of the sights. So, besides my loose groups, which I hope will improve with time and another round of Appleseed next weekend, what am I doing wrong and what, if anything, needs to be adjusted on my AR? EDIT: Link is not properly working for the sight. It's the 40L version at $119.
