Well, as far as ridiculous laws here an CA, I'd be more concerned about handguns than rifles. They've already instituted an assault weapons ban here. If you can get enough money, I'd say go for some .223 AR 15 variant that would be banned were it not for the "bullet button." From what I've read, the bullet button has not actually been approved by the DOJ here, but it hasn't been deemed illegal either. I was at a gun shop out where silverbullets and I live and they have a few AR type rifles with bullet buttons. If you don't know what the bullet button is, you can look at this:
