There are shooting ranges in the United States open to the public, both indoor and outdoor. Either privately owned firearms or those rented from the shooting range may be used, depending on the range rules set by the owner.

Exceptions include cities in the states of Hawaii, California, Massachusetts, New York, New Jersey, Illinois, and Washington, DC, all known for gun control policies in general, where the numbers of ranges may be only one for every few hundred thousand people, or none at all, such as in the Washington, DC case.
