According to the Attorney General in California, it would not be legal to make an AR Rifle using 80% lower receivers. Pursuant to Penal Code 12280, it is illegal to manufacture and sell AR-15's and it is also illegal to possess an unregistered AR-15 rifle. It is also illegal to "cause" and assault rifle "to be manufactured." Therefore, AR-15 rifles cannot be manufactured even if the receivers were only 80% completed.
Now if the AR-15 was modified to not accept more than 10 rounds (permanently fix the magazine), then it has been deemed acceptable by the CA authorities
just so i am clear, If I build an ar rifle to current california legal specs is that acceptable?
If the AR Rifle was permanently modified to not accept more than 10 rounds, then it wouldn't even be deemed an AR Rifle, and therefore, legal to manufacture.
