The only answer
Is to move out of calif. Gun laws will continue to get worse until they have the most restrictive laws in the country. It's my opinion that making "assault rifles" illegal after they were legally purchased is morally wrong. If something is legal when you do it, how can they criminalize it after the fact?
Calguns and CalNRA have been fighting all along, and everything moves backwards, more restrictions, not less. Only hope is winning in courts to overturn UC laws. Good luck.
If you want to move, AZ is right next door, but I will say this - if you move to AZ from a restrictive state, welcome, but do NOT come in here trying to change our laws, we like it the way it is. We get enough people from both coasts who want AZ to become pale parodies of the states they fled, gets old, fast.
If you do come in, I'll be happy to point of the good ranges.
Oh, as for "morally wrong", yes, I agree, from the mores and customs I grew up with and instilled into my by my parents, but you're talking about "ends justifies the means" people, and their end is a completely disarmed population, with only police, military and street thugs to be armed.
Edit to add, do not stop fighting in Cali, didn't mean give up, but I don't see any evidence that anyone is winning anything in Cali - even Nordyke was reversed.
