The people over at Guns.com have put together a a comprehensive report of all the guns banned in California by the “Assault Weapons” ban of 1989 along with some pictures

My favorite part of this stupid law is the “Type 3 Assault Weapons” where the definition is amended to call out specific scary features like Pistol Grip or Thumbhole Stocks. Add to that 1.D guessing this was preemptive to stop criminals from committing robberies and other like crimes with things like Grenades Launchers…

A firearm’s status as an assault weapon under this category is determined solely by its characteristics.
12276.1 (a) Notwithstanding Penal Code section 12276, “assault weapon” shall also mean the following:
