Gun rights advocates have filed lawsuits against Washington states newly signed law that immediately banned the sale of AR-15s and dozens of other semiautomatic rifles.

The National Rifle Associations lobbying arm filed a suit against Washington Attorney General Robert Ferguson and Washington State Patrol Chief John Batiste on Tuesday, the same day that Gov. Jay Inslee (D) signed HB 1240 into law. A second, separate lawsuit was similarly filed against Ferguson, Batiste and four Washington counties sheriffs and prosecutors on behalf of six other opponents.

The NRAs lawsuit, filed on behalf of local plaintiffs and a Connecticut-based firearms trade association, argues that the Second Amendment protects the use and possession of common use weapons, including AR-15 rifles, for self-defense.
