There's a fair amount of talk of confiscation in this thread. IMHO, one of the real problems with discussing confiscation is that we tend to think of it as a "door to door" kind of event. If confiscation ever begins on a large scale, though, I don't think that's how it will go down. I think it will go down much more slowly, much more "under the radar."
Think about the manpower it would take to disarm all of the lawful gun owners in the US at once. If anyone started shooting (I am in no way advocating that they do so), such a scenario has the potential for horrendous losses on both sides. Enough to cripple our military & our economy.
A much more likely scenario, again IMHO, is that the gov't would pick the guns up from one owner at a time. Think about it: Police perform a traffic stop on a gun owner & find a banned AR in the trunk. That's one gun gone. A second gun owner goes through a nasty divorce and his soon-to-be ex-wife reports that he has some of those evil high-capacity magazines. If that's punishable by more than a year in jail, you can bet your bippy that the police will empty his safe while they're in there, because he'll be a prohibited person as soon as he's under indictment. It would take years, obviously, but it would have a much lower potential for losses, or for any kind of organized resistance.
We have to take the political fight to the antis' doorsteps, folks, because time is on their side, not ours.
