Any weapon with "evil features" - if it is a personal weapon, needs to have a fixed magazine. In other words, if you have an AR or similar, you need to get 10 rd mags and install a "bullet-button." Plenty of info on youtube and other sites about this. If it is a military weapon for military use, that is beyond me. To my knowledge there is no way that CA will issue a waiver for an "assault weapon" not in compliance with CA law. Simply reconfigure your weapon to have a 10 rd fixed magazine and you should be good to go. Don't be surprised if the bullet button exception goes the way of the dinosaurs in the near future though - there is no limit to the silliness in Sacramento.
