Here is a picture of my son (age 5). We went shooting today for some practice and father/son time. I had gotton a collaspable stock AR-15 in 22 rimfire setup for the kids. It has adjustable length of pull to fit the whole family, shoots very well and is pretty quite. The 3 shot group you see on the self resetting steel plate he shot from 100 yards over a backpack. We also spent some time learning the duplex hold over and he was able to connect on the plate at 165 yards also. We had a ball today and rest assured when he is old enough to hunt it should be scary.
