The new 'ban' could be as bad as: Banned from owning, no matter when manufactured.
That last one would be making federal felons out of a great many otherwise law-abiding Americans.
You think they don't know that?
In view of the simple fact that felons can do pretty much everthing anyone else can, including vote, in many states ...... with ONE exception: they can not possess a firearm.
If they make enough arcane and unintelligible laws, they can effectively do anything to anybody.
