Here's how it's going to start: There will be a question on your tax return: Do you own any firearms?
It will escalate from there. Everyone will recognize it.
Does anyone think all these people (and there are LOTS of them) will turn in their guns and their 10's of thousands of rounds of ammo? Not. A.
Chance. There's a whole sub-culture of people who have buried their guns and ammo. Many thousands of them.
Meanwhile you can still get lots of AK's, AR's, and bump stocks and their 30 round mags at your local gun show. And Russian surplus ammo by the
boatload for a pretty good price. An AK-74 with a bump stock makes a nice toy.
Semi-Autos are flying off the shelves at record rates, so their "confiscation problem" grows by thousands of guns a day. US citizens will not stand
for gun a gun grab.
