kenjiMR,
Please stop, you're killing me! Never fired? I bought one of my AR's just before the ban also, they were gouging us hard then! The stores couldn't keep AR's in stock.
As to the registration mix up. I work w/several people who knew about the ban and went out and bought lower recievers just before the cutoff date. They also assumed, incorrectly, that it was registered when you purchased it. I mentioned the registration requirement to them about one month before they were due, and they knew nothing about it. The DOJ did a very poor job of advertising it. I only saw the ads very late at night, and only on the History Channel.
Maybe you should check with a lawyer. See if you can prove that, due to minimal advertising and little to no publicity you, and others, were uninformed and were caused, through negligence, or inaction on the part of the CA DOJ to unknowingly commit a crime.
I wonder who has your rifle now?
