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." The commonly used definitions of assault weapons are under frequent debate, and have changed over time. The origin of the term has been attributed to legislators, the firearms industry, gun control groups, and the media. It is sometimes used interchangeably with the term " assault rifle", which refers to selective fire rifles that use intermediate cartridges. After the December 2012

History of terminology

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. The AP Stylebook suggests that newsrooms avoid the terms "assault weapon" and "assault rifle" instead using the term "semi-automatic rifle". Part of the definition of "assault rifle", according to the ''

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

, 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 ssault 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

Political and legislative issues

As of 2012, there are an estimated 2.5–3.7 million rifles from just the AR-15 family of rifles in civilian use in the United States; the total number of assault weapons in the United States among all types is not known, and can not be known because of the different definitions in different jurisdictions.


Defunct U.S. Federal Assault Weapons Ban

The Public Safety and Recreational Firearms Use Protection Act of 1994, more commonly known as the Federal Assault Weapons Ban, expired in 2004. It banned the manufacture or importation of certain semi-automatic firearms that it defined as "semiautomatic assault weapons", commonly known as assault weapons. Any firearms so defined that were already possessed at the time the law took effect were grandfathered in, and could be legally owned or transferred. Another aspect of the law banned the manufacture or importation of magazines that could hold more than ten rounds of ammunition, with existing magazines grandfathered in as legal. The Federal Assault Weapons Ban of 1994 defined certain firearms as assault weapons based on the features they possessed. This included semi-automatic rifles with a detachable magazine and at least two of these features: a pistol grip, a folding or telescoping stock, a flash suppressor or threaded barrel, a bayonet mount, or a muzzle-mounted grenade launcher. It included semi-automatic pistols with a detachable magazine and at least two of these features: a magazine that attaches outside the pistol grip, a threaded barrel, a

, or an unloaded weight of 50 ounces or more. Additionally defined as assault weapons were semi-automatic shotguns with a rotating cylinder, or with at least two of these features: a pistol grip, a folding or telescoping stock, a detachable magazine, or a fixed magazine that can hold more than five rounds. The ban also prohibited 19 specifically named models of firearms, as well as copies of those guns. These included the AK-47,

held a separate news conference in response. There, Feinstein said that it seemed to her "prudent" to register grandfathered assault weapons under the National Firearms Act (NFA). A two-page bill summary on the senator's web site also mentioned registering grandfathered assault weapons under the NFA, but the text of the bill introduced to the Senate did not include that provision. On January 24, 2013, Feinstein introduced S. 150, the "Assault Weapons Ban of 2013". The bill was similar to the 1994 ban, but differed in that it used a one-feature test for a firearm to qualify as an assault weapon rather than the two-feature test of the 1994 ban. On April 17, 2013, it failed on a Senate vote of 60 to 40.
