Today a gunman at Sandy Hook Elementary School allegedly used a .223 caliber rifle to kill at least 27 people, including many children. The video below, courtesy of YouTube user KENFL74, shows a Bushmaster AR-15 shooting .223 ammunition. Many different kinds of guns use this caliber, of course; this is just one example. CNN, however, reports that a .223 Bushmaster was found on the scene. Guns and Ammo has made the case for why AR-15 guns are ideal "home defense" weapons, saying that military-style guns like the AR-15 have always been popular in the U.S. The guns are certainly popular on YouTube, where children of various ages can be seen firing them.
