If you are old enough o die for your country with an M16 in your hands. You are old enough to own an AR15
On the other hand, I have no problem requiring anyone wishing to purchase a fire arm to attend a basic gun safety course and fire arm training course before they are allowed to posses a gun.
Even that requirement is not supported by fact because fire arm accidents are very rare, even with the almost universal lack of training for firearms owners these days.
Any kind of unlawful use of rifles is so rare that more people are killed by lightning strikes than rifles of all types, much less AR15s

Just another tax. I first used a gun at the age of 5, more than 60 years ago. I don’t need no steenking course.
