Assault weapons legislation in the United States refers to bills and laws (active, expired, proposed or failed) that define and restrict or make illegal the manufacture, transfer, and possession of assault weapons.
 How these firearms are defined and regulated varies from jurisdiction to jurisdiction.
 In general, there is no clear definition of an "assault weapon."
 Nonetheless, "assault weapons" are often considered to be semiautomatic firearms with a large magazine, as first defined in a 1994 Federal Assault Weapons Ban (AWB)."
The Roberti-Roos Assault Weapons Control Act of 1989 banned Colt AR-15 rifles by name in the State of California.
 California's 2000 Assault Weapons ban went further and banned AR-15s made by other manufacturers by name such as Bushmaster, PWA, and Olympic Arms.
"Silveira v. Lockyer," 312 F.3d 1052 (9th Cir.
 2002), is a decision by the United States Court of Appeals for the Ninth Circuit where that appeals court ruled that the Second Amendment to the United States Constitution did not guarantee individuals the right to bear arms.
 The case involved a challenge to the Constitutionality of the Roberti-Roos Assault Weapons Control Act (AWCA).
 California legislation banned the manufacture, sale, transportation, or importation of specified semi-automatic firearms.
 The plaintiffs alleged that various provisions of the AWCA infringed upon their constitutionally guaranteed right to keep and bear arms as individuals.
The Federal Assault Weapons Ban (AWB) — officially, the Public Safety and Recreational Firearms Use Protection Act — is a subsection of the Violent Crime Control and Law Enforcement Act of 1994, a United States federal law that included a prohibition on the manufacture for civilian use of certain semi-automatic firearms it defined as assault weapons, as well as certain ammunition magazines it defined as "large capacity."
A Federal Firearms License (FFL) is a license in the United States that enables an individual or a company to engage in a business pertaining to the manufacture or importation of firearms and ammunition, or the interstate and intrastate sale of firearms.
 Holding an FFL to engage in certain such activities has been a legal requirement within the United States since the enactment of the Gun Control Act of 1968.
 The FFL is issued by the Bureau of Alcohol, Tobacco, Firearms, and Explosives (BATFE, commonly known as the "ATF").
Assault weapon is a term used in the United States to define some types of firearms.
 The definition varies among regulating jurisdictions, but usually includes semi-automatic firearms with a detachable magazine and a pistol grip, and sometimes other features such as a flash suppressor or barrel shroud.
 Some firearms are specified by name.
 At the time that the now-defunct Federal Assault Weapons Ban passed in 1994, the U.S. Justice Department 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 origin of the term has been attributed to legislators, gun control groups, the media, and the firearms industry itself.
 It is sometimes conflated with the term "assault rifle", which refers to selective-fire military rifles that can fire in automatic and / or burst mode.

Gun laws in Connecticut regulate the sale, possession, and use of firearms and ammunition in the state of Connecticut in the United States.
 Compared to other states, Connecticut's firearms laws are moderately restrictive; with strict training, background check and permitting requirements for the purchase of firearms and ammunition; and a ban (with exceptions) on certain semi-automatic firearms defined as "assault weapons" and magazines that can hold more than 10 rounds.
 In contrast, Connecticut's licensing system for open and concealed carry is relatively permissive.
The Roberti-Roos Assault Weapons Control Act of 1989 (AWCA) is a California, United States, law that made illegal the ownership and transfer of over fifty specific brands and models of semi-automatic firearms classified as assault weapons.
 While mostly rifles, some were pistols and shotguns.
 The law was amended in 1999 to restrict acquisition and transfer of magazines that could hold more than 10 rounds of ammunition.
 Firearms and magazines that were legally owned at the time the law was passed were grandfathered in if they were registered with the California Department of Justice DOJ.
