I have access to an M16A2 and a private range. I just picked up my .22lr upper yesterday, and am looking forward to shooting it. But, will it work on an NFA lower? I suspect that it won't since standard uppers require the full auto bolt, and I am assuming the .22lr upper is not configured that way. Can someone offer any advice or experience? Three round burst of .22lr is a good way to spend an afternoon, you know?
