AR-15 fires a .223 (22 calibre) bullet. Not Designed to Kill people, primarily wounds people. Most hunting riles are 30 cailber and designed to kill creatures much larger than a person. So... I'd much rather be shot with an AR-15 than shot once with any given hunting rifle. So much for taking dangerous guns off the market just because they are made with plastic handles that look scary.
Also, for those who don't understand the nomenclature, AR stood for Armalite who originally developed the designs for the semi-automatic AR-15 and the automatic M-16, AR does not stand for Automatic Rifle. The true Automatic rifle in this case is now designated M-16 which is what the military uses, and is already illegal to sell to civilians.
