3D animation of AR 15 Trigger functioning

The AR 15 Trigger might seem complicated, but it is actually a beautifully simple mechanism.
First, the Safety Selector prevents the Trigger from raising far enough to release the hammer.
With the Safety selector set to the fire position, the trigger can move into the cut-out on the inside portion of the Safety.
The Trigger Sear and the Hammer surfaces are engaged. The Firearm is now waiting for you to pull the Trigger.
Once you pull the trigger, these surfaces disengage, allowing the Hammer to rotate forward.
Spring pressure drive the Hammer forward, firing a round.
Gas pressure drives the Bolt Carrier Group rearward, this pushes the hammer back.
The hammer latches onto the Disconnector. This prevents the Hammer from rotating forward, while you hold the trigger to the rear.
As you release the Trigger, the front of the Disconnector is pushed up. This disengages the Hammer and disconnector.
Just prior to disconnecting, the Trigger Sear is in position to catch the notch in the Hammer, preventing it from rotating forward until you pull the Trigger again.
Please don't steal this animation. It took a long time to put together. If you would like to use it for any reason, please send my a PM and we will work something out.
