"The distinctive “look” of assault weapons is not cosmetic. It is the visual result of specific functional design decisions. Military assault weapons were designed and developed for a specific military purpose — laying down a high volume of fire over a wide killing zone, also known as “hosing down” an area. The most significant assault weapon functional design features are: (1) ability to accept a high-capacity ammunition magazine, (2) a rear pistol or thumb-hole grip, and, (3) a forward grip or barrel shroud. Taken together, these are the design features that make possible the deadly and indiscriminate “spray-firing” for which assault weapons are designed. None of them are features of true hunting or sporting guns. Civilian semiautomatic assault weapons incorporate all of the functional design features that make assault weapons so deadly. They are arguably more deadly than military versions, because most experts agree that semiautomatic fire is more accurate than automatic fire. Although the gun lobby today argues that there is no such thing as civilian assault weapons, the industry, the National Rifle Association, and gun magazines enthusiastically described these civilian versions as “assault rifles,” “assault pistols,” and “military assault” weapons to boost civilian sales throughout the 1980s. The industry and its allies only began to use the semantic argument that a “true” assault weapon is a machine gun after civilian assault weapons turned up in large numbers in the hands of drug traffickers, criminal gangs, mass murderers, and other dangerous criminals."
