I was at the range today with my buddy and his youngest daughter (14 year old). She has been doing well in school, so her dad said she could throw some lead down range. She did ok for not shooting for 6 months or more. She worked through a few boxes on the H&R 22LR using the aperture sights.
There was a guy next to us with a national match ar-15. I seldom see the traditional style stock, so I asked him about it as we were heading out. He talked about it a little, and let me shoulder it. I have to go in for a hernia check. The ar-15 weighed 17 lbs. Yes, SEVENTEEN! I didn't have a spotting scope going, but I bet he was well under 1 moa.
