Drawing from federal and state law definitions, the term assault weapon refers primarily to
semi-automatic rifles,
pistols, and
shotguns that are able to accept detachable magazines and possess one or more other features. Legislative definitions do not include fully automatic weapons, which are regulated separately as
Title II weapons under federal law. At that time, the
United States Department of Justice said, "In general, assault weapons are semiautomatic firearms with a large magazine of ammunition that were designed and configured for rapid fire and combat use." Common attributes used in legislative definitions of assault weapons include: •
Semi-automatic firearm capable of accepting a
detachable magazine; • A
pistol grip that protrudes beneath the
action of the weapon; The
Merriam-Webster Online Dictionarys definition is "any of various automatic or semiautomatic firearms; especially: assault rifle".
History of terminology The origin of the term is not clearly known and is the subject of much debate. In the past, the names of certain military weapons used the phrase, such as the
Rifleman's Assault Weapon, a grenade launcher developed in 1977 for use with the
M16 assault rifle, or the
Shoulder-launched Multipurpose Assault Weapon, a rocket launcher introduced in 1984. One of the earliest uses of the term, or a similar term, in its current meaning was as part of an advertisement in
The Hutchinson News (Kansas) in 1978 for the
Valmets-7.62×39, the
Colt AR-15, and the
Wilkinson Terry carbine. Another was in a bill introduced by
Art Agnos in the
California State Assembly in April 1985 to ban semi-automatic "assault firearms" capable of using detachable magazines of 20 rounds or more. Speaking to the Assembly Public Safety Committee, Agnos said, "The only use for assault weapons is to shoot people." Phillip Peterson, the author of ''Gun Digest Buyer's Guide to Assault Weapons'' (2008) wrote: Meanwhile, many gun rights activists have put forward that the term was popularized by the media or gun control activists. Conservative writer
Rich Lowry said that assault weapon is a "manufactured term". Joseph P. Tartaro of the
Second Amendment Foundation (SAF) wrote in 1994: "One of the key elements of the anti-gun strategy to gull the public into supporting bans on the so-called 'assault weapons' is to foster confusion. As stated previously, the public does not know the difference between a full automatic and a semi-automatic firearm." Robert Crook, executive director of the Coalition of Connecticut Sportsmen, said "the term 'assault weapon,' as used by the media, is a media invention."
Gun control supporters use the term while
gun rights supporters generally do not use the term.
Differing state law definitions Seven states have assault weapon bans with different definitions and characteristics. •
California defines assault weapons by name, by "series" (
AK-47 or
AR-15), and by characteristic. A shotgun with a revolving cylinder is also defined as an assault weapon. •
Maryland defines and bans assault
pistols. It regulates 45 other assault weapons listed by make or model including copies, regardless of manufacturer. •
Massachusetts defines assault weapons as semi-automatic firearms with the same definition provisions from the expired federal ban of 1994. •
New York had an assault weapons ban prior to 2013, but on January 16 of that year it passed the
SAFE Act, which created a stricter definition of assault weapons and banned them immediately. The NY SAFE Act defines assault weapons as semi-automatic pistols and rifles with detachable magazines and one military-style feature, and semi-automatic shotguns with one military-style feature. The Illinois State Rifle Association said most of the state's firearms owners owned one or more guns that would have been banned under the proposal. The NRA said the proposal would have restricted about 75 percent of handguns and 50 percent of long guns in circulation.
Minnesota also defines certain firearms as assault weapons and regulates their sales.
Distinction from assault rifles The term "
assault rifle" is frequently used interchangeably with the term "
assault weapon" but this use has been described as incorrect and a misapplication of the term. Part of the definition of "assault rifle", according to the
Encyclopædia Britannica, is that it is selective-fire, which means that it is capable of both semiautomatic and fully automatic fire. Civilian ownership of
machine guns, including selective-fire rifles, has been tightly regulated since 1934 under the
National Firearms Act and since 1986 under the
Firearm Owners Protection Act. In May 2012, the
Law Center to Prevent Gun Violence said, "the inclusion in the list of features that were purely cosmetic in nature created a loophole that allowed manufacturers to successfully circumvent the law by making minor modifications to the weapons they already produced." Some reporters used the term in stories after the 2012 shootings in
Aurora, Colorado, and
Newtown, Connecticut. Assault weapons, also sometimes called "black guns" or "black rifles", are no more powerful than many other semi-automatic rifles legally used for hunting throughout the United States; they do not shoot faster or have greater range. Two scholars have written: "One problem inherent in the study of [assault weapons (AW)] is that the classifications of AW are based on cosmetic features of firearms... For instance, the Colt AR-15 series of semi-automatic rifles—the civilian version of the fully automatic M-16 rifle issued to U.S. soldiers—was subject to the 1994 AW restrictions, but the
Ruger Mini-14 rifle was not banned. Yet, the Mini-14 is the same caliber, has a similar barrel length, the same semi-automatic action, and can use magazines that hold 30 rounds of ammunition. The only real meaningful difference between the two firearms is cosmetic: The AR-15 rifle looks more dangerous." The
National Shooting Sports Foundation, a firearms industry
trade group, states that the term
assault weapon has been misapplied to many semi-automatic firearms because of their appearance and not their use in crime. ==Political and legislative issues==
