This part is the trigger which we also designed from scratch. By looking at the front view you can tell which way your finger is supposed to work. When you pull on the trigger with yoru finger you can see that their will be a moment created around the top left part of the trigger in the front view. This moment will cause the firing hammer to go off. To fully understand how this works you will have to compare this to the assembly drawing. To go to the assembly drawing click on the cad button to your left.
