They are legal, depending on the type. But they are also regulated to varying degrees depending on which state you live in. In some states, you simply have to register and pass a quick background check to purchase so they can verify you comply with certain laws preventing certain categories of individuals from ever owning (violently insane, and anyone with a criminal conviction on their record) In other areas, firearms are very heavily regulated (California, New Jersey, and Disctrict of Columbia having some of the strictest laws). The requirements also vary depending on the intended usage: A public "Carry" permit obviously having much higher standards than simple ownership/transport to/from the range.
