Doesn't have to do that. Already have precedent laws can restrict the types of arms people can carry (assault weapons ban, you can't build a nuke and say the 2nd amendment protects it).
So obviously a huge restriction on gun types, magazine sizes, etc would be available.
The big one that I see would be a "national emergency" saying that guns are 2200% more deadly in the US than illegal immigrants and then not touch the 1st amendment, but create a clear and simple path for families of victims to hold gun makers and ammunition makers financially responsible. That doesn't touch anyone's right to own. But it would end the gun industry for private sale in the US.
That's what scares me about declaring an emergency to take away money from our military and build a wall where the majority of illegal immigration and drug smuggling are not occurring.
Yes, but, sadly, all of those laws on firearm types of restrictions are technically unconstitutional as well. The words "shall not be infringed" apply here.
One of the things the left like to do is take things to the extreme and say "well, does that mean you should be able to own a tank, or rockets, or nukes?". My answer to that is, when the framers were writing the 2nd, it's clear by the text of the amendment, and by supporting documents (federalist papers), they were referring guns, muskets being what they had at the time. The 2nd amendment was written In 1791, the first automatic weapon wasn't made until 1892.
