He lives in Cali. and has an AR which has the "bullet button" and 10-round magazines and required him to get a background check and go through a waiting period. If you buy from a dealer there, you don't have4 a choice. He suggests that when the government calls for you to turn the guns in, that's where you should refuse to comply.
Bad idea Bill. When it gets to that stage it's way too late for non-compliance. The red line for non-compliance is when they ask you to register the gun. Without registration, and with face-to-face sales without checks, whether a person actually has the gun in question is questionable. It's difficult to get a search warrant on those kind of shaky grounds. Not impossible, mind you, but somewhat more difficult.
Update: Just found this:
"Still, if you will not fight for the right when you can easily win without bloodshed, if you will not fight when your victory will be sure and not so costly, you may come to the moment when you will have to fight with all the odds against you and only a precarious chance for survival. There may be a worse case. You may have to fight when there is no chance of victory, because it is better to perish than to live as slaves." Winston Churchill
