A mode of fire found on various assault rifles in the world. Most popular of which is the M16A2 used by the US military. It acts as a fully automatic rate of fire until the third round after which the mechanism will not fire until the triger is pulled again. It is comonly misconcieved that one pull of the trigger always fires tree rounds, 1,2, or 3 rounds may be fired.
