Huh I stand corrected. I've seen ATF agents[1], FBI agents [2], as well as US district attorneys[3] incorrectly refer to semi-automatic AR-15s as "assault rifles" (which in actual fact are subclasses of machineguns), but since they charged him with that I assume it really must be a machinegun then. But now I'm really curious to know more specific details about this firearm. Particularly if it was a legally transferable machinegun (legal federally, obviously not in California), or if it was an illegally modified semi-automatic (probably most likely) or a black market gun.
