AR-15 stands for "Armalite Rifle", not "Assault rifle" or God forbid "Automatic rifle" because it's the semi-auto civilian version of the M4.

AR 15 

AR 15 is the civilian version of the military's M4 carbine. Contrary to what most people believe AR doesn't stand for assault rifle, rather it stands for the original manufacturer Armalite Rifle. AR 15 is semiautomatic and does't meet Federal requirements to be classified as an assault rifle.

AR 15 is so legal in Kalifornia, now everyone is sporting it
