Arizona’s firearms laws are few and generally liberal. The following specific restrictions apply:  The discharge of a gun may be in violation of various laws, including discharging across a highway, within 1/4 mile of a residence, in the direction of another person, and more. Most cities and towns have local ordinances against discharge within their jurisdictions. In all cases where a production includes the discharge of a weapon, it is appropriate to contact the local police department to determine the state/local laws applicable to the area of the production.
