What is a disconnector, and why do I need one?
A disconnector breaks the firing cycle by interrupting the connection between the trigger and sear, i.e.., “disconnecting” the trigger. This keeps the gun from firing again and again, without the need to pull the trigger for each shot. In a system that would fail to fire again and again, it assures that the firing mechanism is reset, so that when the trigger is released, it will be ready to fire when the trigger is pulled again, eliminating the need to re-cock it between shots. The BATFE defines full automatic as the discharging of more than one shot per pull of the trigger. Therefore, you need a disconnector to keep the gun from being an illegally made full automatic weapon.
