A FOX news story from Thursday, Oct. 3, 2013 says the National Rifle Association (NRA) plans to sue the state of California if Governor Jerry Brown signs a bill that bans the future sale of most semi-automatic rifles that accept detachable magazines.

The article says the bill, sent to Brown last month, would outlaw an entire class of weapons that includes most “assault rifles,” and change the assault-weapon definition to include any semi-automatic rifle with a detachable magazine or a fixed magazine that holds more than 10 rounds. On its website, the NRA said the bill is unconstitutional and “would make unprecedented changes to California’s already unjust and byzantine ‘assault weapon’ law.”

“Our right to keep and bear arms has never been as seriously threatened in California as it is today. After years of incrementally adopting gun control measures, this year the Legislature decided to propose new laws adopting everything on the gun ban lobby’s wish list,” the group said last Tuesday.

Other bills waiting for Brown’s approval include a restriction to ammunition sales and another concerning who can legally possess firearms. However Brown does not have a consistent track record when it comes to signing firearm legislation, and he has until Oct. 13 to either sign or veto the bills.
