This go round will be different because the same clowns that passed the first one are still in office and learned from their mistakes.
If the dems take both houses and the white house you won't own a semi-auto anything. Plus they will probably declare any rifle that will accurately shoot more than 100 yards a sniper rifle.
My 2 cents
Only if gun owners are willing to comply. If every semi-auto gun owner and accuracy rifle owner flips the bird to the feds, well there is not much they can do about it. But, it has to be the majority of those gun owners and some backing by the state government. Example - legalization of marijuana at the state level by the various states. In essence, the states have flipped the bird to the feds.
