Looks more and more like nobody knows whata firearm is. Automatic weapons are illegal and I highly doubt Hardy owns any.
Automatic weapons are not illegal. You just need a $200 tax stamp and boatload of cash to buy one. And I believe it takes about 8 to 12 months for the Feds to process and approve after you apply for the stamp. It's also basically the same process for buying a suppressor.
Now, if you own an automatic weapon and don't have the proper paperwork, you're fuged.
