Looks like this link will answer it http://en.wikipedia.org/wiki/Semi-automatic_rifle
I've heard folks say they CAN convert semi to auto, BUT from the regulations mentioned above it appears to be illegal.
what should be addressed is the absolute BAN of all assault weapons…...Right. It should be illegal. I was only asking because if fully automatic was not sold to civilians but they can convert a semi automatic with a magazine then that is a loophole that should be addressed.
