"locked out" means what?
A relative in a very anti-gun state has a friend who just inherited a bunch of black guns. Among them is an AR auto which has been "locked out", supposedly making it a legal semi-auto.
I don't know what that means. I suspect it may be a selective fire that is only set at semi. That would mean the rifle is really a machine gun and the current owner might be subject to a lot of Federal doo-doo if he doesn't act quickly and turn over to the Feds.
I am I right or wrong on this?
