Final answer:
A short-barreled rifle is defined by having a barrel length of less than 16 inches or an overall length of less than 26 inches. These measurements determine the classification and legal handling of the weapon.
Step-by-step explanation:
A short-barreled rifle is defined as having one or more barrels less than 16 inches in length OR any weapon made from a rifle that has an overall length of less than 26 inches. These regulations have been put in place to control the types of weapons that are in circulation and to ensure public safety. Laws surrounding guns vary, but in many jurisdictions, these specific measurements are important legal distinctions that classify the weapon and its associated regulations, such as licensing and handling requirements. For example, police could issue one-year licenses for handguns and might require that owners of lawfully registered firearms keep them unloaded and disassembled or secured with a trigger lock or other similar device unless the firearms are located in a place of business or being used for legal recreational activities.
