Fine, arrest and prosecute them for illegal arms sales if they are caught.Good luck getting criminal gangs, white supremacists, prepers & those who think it is none of your God-damn business to honestly declare all gun sales and transfers.
Then arrest and prosecute the gun manufacturers and gun shop owners who sell guns without filling out the paperwork.Only if gun makers and gun shops agree to stop making and selling any more guns.
If you want to make a gun yourself, have fun.
If you want to keep a gun you already own, have fun.
If you want to buy a 50 caliber autocannon for duck hunting, fill out the paperwork and have fun.
I really don't see the problem here. The 2nd Amendment talks about a "well-regulated" militia. Not sure how secret gun ownership fits in with that.
