When I was regularly shooting it was common knowledge that it only takes a few minutes to modify an AK47 from semi to full, or an AR15 to be an M16. To me in that one point it should be acknowledged that any idiot with a tool kit would be buying a soon to be fully automatic weapon when he purchases one of these guns. What in the devil are people doing with them anyway? I've spent many hours firing an M16. They are not the best for targets, lousy for precision hunting (ie. long distance or small game) and perhaps only good for wasting ammo. Ammo is too expensive to waste in my family. We have a one bullet, one kill policy.
(it was nice of the Army to give me all those rounds when I was shooting an M16)
