Rumor has it, the BATFE is going to be starting a public comment period on reclassifying bump stocks and other devices as NFA "machine guns.". (

Let's say they do reclassify them as NFA items. With the Hughes Amendment in place, what would/could happen to currently owned ones? Does the ATF have to grandfather them, reimburse owners for taking them, or neither? Previous laws tended to grandfather items, but since the MG registry is closed, would owners be forced to destroy them? Would that not invoke the takings clause and entitle them to compensation?
I have a passing understanding of a lot of these principles, but not how they would/could interact in practice.
