CA does not have an assault weapons ban. However they do ban the transfer of any weapons that they consider an assault weapon. So, what does CA consider an assault weapon. Well according to CA penal code 12776.1 any semi-automatic, centerfire rifle that has the capacity to accept a detachable magazine and has any one of the following features would be considered an assault weapon. Those features are:
- A pistol grip that protrudes conspicuously beneath the action of the weapon.
- A thumbhole stock.
- A folding or telescoping stock.
- A grenade launcher or flare launcher.
- A flash suppressor.
- A forward pistol grip.
I have attached the Rifle Flow chart from CalGuns here for a more detailed explanation.
And here is a memo that was distributed with in the Sacramento Police Department.
