Automatic Firearm

ȯd·ə¦mad·ik  ′fīr‚ärm

An automatic firearm is any firearm that will continue to fire so long as the trigger is pressed and held and there is ammunition in the magazine/chamber. While both "semi automatic" and"fully automatic" weapons are "automatic" in technical sense that the firearm automatically cycles between rounds with each trigger pull, under conventional usage a merely semi-automaticfirearm is not correctly referred to an "automatic weapon" or an "automatic firearm". The terms "automatic weapon" and "automatic firearm" are conventionally reserved to describe fullyautomatic firearms. Confusion can be avoided by this convention. A semi-automatic firearm fires one round with each individual trigger pull, while a fully automatic continuously fires roundswhilst the trigger is pressed and held.


The speed of fully automatic firearms is measured in rounds per minute (RPM) or rounds per second (RPS), in what is called the Rate of fire. The speed of fully automatic firearms iscompared to each other this way.
