Automatic firearm

Automatic firearm

An automatic firearm is a firearm that automatically extracts and ejects the fired cartridge case, and loads a new case, usually through the energy of the fired round. The term can be used to refer to semi-automatic firearms, which fire one shot per pull of the trigger, or fully automatic firearms, which will continue to load and fire ammunition until the trigger (or other activating device) is released or until the ammunition is exhausted. An "automatic pistol" or an "automatic shotgun" generally refers to a semi-automatic design, while "automatic rifle" more often means a fully automatic or selective fire design.

Fully automatic weapons tend to be restricted to military and police organizations in most developed countries. In the United States, machine guns registered after 1986 have been off the public market since the Firearm Owners Protection Act of 1986, though on April 21, 2008, Governor Kathleen Sebelius signed a bill allowing the sale and possession of NFA weapons in Kansas. The law took effect on July 1, 2008.

Fully automatic firearms are covered in these articles:
*Machine gun
**General purpose machine gun
**Heavy machine gun
**Light machine gun
**Medium machine gun
**Squad automatic weapon
*Submachine gun
*Assault rifle
*Automatic rifle
*Machine pistol

Other similar designs not usually classified as automatic firearms are:
*Autocannon, which are 20 mm in bore diameter or larger and thus considered cannons, not small arms.
*Gatling guns, multi-barrelled bolt-action designs, often used with external power supplies to generate rates of fire higher than automatic firearms.

Similar in appearance but not able to fire in full-auto mode are some semi-automatic rifles. The visual similarity has led to the public usage of the term assault weapon to describe some semi-automatic weapons (as opposed to the military usage of the term).
