| What is the purpose of the disconnector? Just curious. |
| Yhis is what I think it does. It retains the hammer in the rear position during the time period that the trigger is pulled into the firing position. It continues to retain the hammer as the trigger is released untill the trigger is in a position that it can again begin to retain the hammer. |

In the animation the disconnector is the green hook, the sear is the front edge of the trigger mechanism (blue) that retains the hammer in the cocked position. After a shot is fired, the disconnector stops the hammer from dropping until the trigger is released and the sear engages the sear-notch at the rear of the hammer. This is what stops the hammer from dropping when rearward trigger pressure is retained during semi-automatic fire. And no, filing off the disconnector hook will not make your weapon fully automatic, it will however make it a single shot, as the hammer will chase the bolt-carrier and will not exert enough force on the firing pin to crush the primer on the subsequent shot. |

The animation is correct. When it begins, it is showing what happens when there is no trigger pressure and the bolt is brought tp the rear, cocking the hammer on the sear. The trigger is then depressed, moving the sear downward off of the sear engagement notch in the hammer. The hammer then falls forward, firing the shot. There is still rearward pressure on the trigger from the trigger finger, which means that the sear engagement notch on the hammer cannot set-up on the sear. This is why there is a disconnector. The disconnector catches on the disconnector hook on the hammer (at the back of the hammer, near the top), retaining the hammer to the rear. As long as there is rearward pressure on the trigger, the disconnector will be the part that is holding the hammer to the rear. As trigger pressure is released, the disconnector releases the hammer to begin moving forward, but is stopped by the sear engaging the sear notch on the bottom rear of the hammer. The trigger is pressed, and the cycle starts again. |
I disagree about the video. The trigger is not high enough at the front to catch the hammer notch at the time when the hammer is released by the disconnector. At least thats they way it looks to me when I stopped the video at the point of release by the disconnector. |

The problem with the animation you are seeing, is there is no Selector installed. That allows the trigger to move too far (in real life, it wouldn't work too well, but it is an animation, not real life). The Disconnector is the "green" part in the animation and it's function is to grab and hold the hammer (after a trigger pull) until the pressure is released from the trigger. It then releases the hammer onto the trigger sear, readying for the next shot. You can hear it work in an empty rifle by cocking, pull and hold trigger, then re-cock, and let the trigger pressure off slowly. You will hear and feel a click, that is the disco releasing the hammer onto the trigger sear (also known as "Reset". Hope that helped.  |
