Sighted in my AR this am. Didn't have much time so I only shot it at 50 yards. Shot great and a tiny grouping as expected. I also bump fired it! My father in law was walking up behind me when I did it and he freaked out. He was asking what I had done to it to make it shoot full auto it ran through the mag a little too quick. He made a video of me bump firing 10 rounds but it is on his phone. I'm going to have to get him to send it to me later. Maybe I can post it on here
