The easy answer is to find a state with like minded folks. Maybe those same guns are legal in that state. Now, get the Attorney General to file on the basis of the state that the Federal law violates the Constitution of the United States. That's pretty much an express ticket to the Supreme Court, the same court that has gutted states rights since FDR's reign of terror.
The other legal method is to get your state senator/congressperson to write a bill repealing the existing bill, pointing out that the bill is useless, creating an unneeded agency, who's day and existence is no longer necessary. That law was originally intended to stop the Kennedy's from doing their whiskey, and scotch running stuff. Now they are legit, and in congress, so, we don't need the law anymore it worked.:barf:
Third choice is to create, and organize a group that will help sponsor an amendment to The Constitution, or State Constitution, that the regulation of machine guns is a state 's right, not the Federal governments, and, hopefully again you will be in Federal court.
Another way being attempted in Wyoming right now is a law passed that the local sheriff is the Supreme Law enforcement agency in that state. The law requires that before any warrant/legal action/etc. takes place in the county of Wyoming, the local sheriff must be informed, able to review, and accept or reject the legal action by the federal government, and be involved in the action to serve said person.
If it's rejected, the first step would be for the Federal Government to file in state court, go through that state's appeals process, and Supreme Court, and, then they could appeal into Federal Court, Supreme Court, much as us lowly regular folk have to proceed.
