Gun laws in the United States regulate the sale, possession, and use of firearms and ammunition. State laws (and the laws of Washington, D.C. and the U.S. territories) vary considerably, and are independent of existing federal firearms laws, although they are sometimes broader or more limited in scope than the federal laws. A minority of U.S. states have created assault weapon bans that are similar to the expired federal assault weapons ban.
State level laws vary significantly in their form, content, and level of restriction. Forty-four states have a provision in their state constitutions similar to the Second Amendment to the U.S. Constitution, which protects the right to keep and bear arms. The exceptions are California, Iowa, Maryland, Minnesota, New Jersey, and New York. In New York, however, the statutory civil rights laws contain a provision virtually identical to the Second Amendment. Additionally, the U.S. Supreme Court held in McDonald v. Chicago that the protections of the Second Amendment to keep and bear arms for self-defense in one's home apply against state governments and their political subdivisions.
A firearm can be used primarily as a tool, instead of as a weapon, to project either single or multiple objects at high velocity through a controlled explosion. The firing is achieved by the gases produced through rapid, confined burning of a propellant. This process of rapid burning is technically known as deflagration. In older firearms, this propellant was typically black powder, but modern firearms use smokeless powder, cordite, or other propellants. Many firearms such as mortars do not have rifled bores to impart spin to the projectile for improved flight stability, such as is seen with firearms used as weapons, although some are rifled. The lack of rifling can prevent tangling of grappling hook lines, buoy lines, and such, although some firearms intended for use at the longest ranges in these applications are rifled.
