Today there was some kid and his dad shooting their new AR. Only problem is they had no idea how to work it, and they didn't have a rear sight. Yep, just a FSB and nothing on the A3 receiver. I had to show them how to use the bolt release to get a round to chamber because they kept riding the charging handle forward and the thing wouldn't go into battery. Once they got the whole "loading the weapon" thing squared away they had a hell of a time aiming. They were shooting at 50 yards, and the dad put a round into the dirt about 20 rounds in front of the target. I looked to see their hits when I went to take my target down when I was done, and of about 30 rounds they got exactly TWO hits on the paper. The targets are 21x24 inches.
