The antifederalists wouldn’t ratify the US constitution without the bill of rights. These rights are inalienable and are from God. These are not privileges or allowances from any ruler or government.They cannot be infringed by the government.

However, if they didn’t make the firearm with readily available materials, it should be illegal for them to purchase them from a seller. Kind of like marijuana decriminalization proponents, legal to possess, illegal to buy. But you can’t just grow a firearm… you could get a 3D printer and make a ghost gun.

I dunno, just spitballing here.
