Anyone that can qualify to own a class III Federal firearms license to shoot a fully auto weapon I have no issue with. They are very well checked out and stable collectors. Not a threat. I own many semi auto handguns and rifles. Other than my semi auto shotgun, they are not very good for hunting. Target shooting yes.   The AR and AK biggest problem is that in gun shows, unstable folks and criminals can get them with no check. Add a 100 round drum magazine and it gets sketchy for sure. So fix the loophole.

I have had lots of fun firing fully auto weapons ... and they belonged to the sheriff's office. I know lots of people who like to shoot and don't hurt anyone
