Stu is absolutely correct, sport and hunting is not the issue, whytthe hell do we allow weapons of war.. Some sports men will tell me they use their hunting. My response, get the proper rifle for hunting that is not the one any true hunter wants and illegal to hunt with in many states. We just don't need them. We have common sense laws on what is a street legal car. You can't have nitrous oxide tanks on the street. So why not weapons.. If you competition shoot, you use a bolt action rifle, same for hunting.. That shooter had one of the newer versions of a stoner rifle modified for full auto replacation.. Why... For war not sport
