Remember how I said that every state defines an assault weapon differently? Here is part of it:

Differing state law definitions[edit]

Main article: Assault weapons legislation in the United States

Seven states have assault weapon bans with different definitions and characteristics.^[27]

• California defines assault weapons by name, by "series" (AK-47 or AR-15), and by characteristic.^[28] A shotgun with a revolving cylinder is also defined as an assault weapon.^[12]
• Connecticut defines assault weapons as selective-fire firearms (including assault rifles capable of fully automatic or burst fire); semi-automatic firearms specified by name; and semi-automatic firearms with specific characteristics.^[13]
• Hawaii defines and bans assault pistols.^[29]
• Maryland defines and bans assault pistols. It regulates 45 other assault weapons listed by make or model including copies, regardless of manufacturer.^[29][30]
• Massachusetts defines assault weapons as semi-automatic firearms with the same definition provisions from the expired federal ban of 1994.^[31]
• 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.^[32][33][34] 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.^[33]

In Illinois, proposed legislation in 2013 would have defined the term "semi-automatic assault weapon" as any semi-automatic firearm able to accept a detachable magazine, but it was never brought to a vote.^[35][36] 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.^[37] The NRA said the proposal would have restricted about 75 percent of handguns and 50 percent of long guns in circulation.^[37] As municipalities, Chicago and Cook County bans certain firearms defined as assault weapons and have no provision for legal possession of firearms owned before their laws were passed.^[38][39] Minnesota also defines certain firearms as assault weapons and regulates their sales.^[29] The State of Washington defines any semi-automatic rifle (except antiques), regardless of features, caliber, or magazine type, as a "semiautomatic assault rifle".^[40]

Distinction from assault rifles[edit]

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.^[8] The AP Stylebook suggests that newsrooms avoid the terms "assault weapon" and "assault rifle" instead using the term "semi-automatic rifle".^[41] 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.^[42] 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.^[11]
