I don't have to think of as anything but illegal. A semi auto is a semi auto until it is permanently made into a rifle that can no longer shoot in a semi auto mode. It would be easy enough for a person to field strip a rifle and remove the part that makes it a semi if he sees someone approaching him. That is why it is not legal to do a temporary fix. I am not going to argue with you, I know how the law is enforced, I enforced it for over 30 years and I know what the PGC tells people who ask if they can make a temporary fix to a semi auto gun. No good comes of telling people they can get away with an illegal act.
