He appeared to be very well trained, an no, I don't think it is too young as long as the child understands and follows the trainging they are given (and are closely supervised). I got my first .22 rifle at five years old (right after I showed I could handle a Red Ryder). Dad had to saw off the barrel and the stock a little bit so I could hold it up and shoot it (a singel shot rifle with a peep sight).
