This is an eye opener. I guess what I said about the age limits may be only Arizona. Many laws were discussed. Sometimes he did not distinguish between federal law and state law. I am going to have to talk to that NRA instructor. I imagine the article is truthful, but I sent an email to that instructor. He is a friend of mine. I am very interested in what he has to say.

Update: (I just realized that after posting this update that my posts is a bit off topic. OOPS)

I am going to quote that article here. It says “He bought it about a year ago, when he was 18, at which point Florida law allowed him to buy a long gun like the AR-15. Then there is also this “He’s too young to buy a handgun or a beer, but he’s old enough to buy a rapid-fire rifle”. This supports what I think is federal law. However “In 10 states, in fact, he was older than he legally needed to be: In nine of those states, people younger than 18 can buy long guns with their parents’ permission”. Please note that they are talking about rifles, not hand guns. However, you appear to be correct in that some states made it lawful for 16 years old can purchase a rifle. This is a bit scary to me. They should not be able to purchase semi-automatic weapon for any reason. But a single action may make sense, like for hunting deer. They do not need a semi to hunt deer.
