Algodoo

This is a close-up internal view of the tri-burst trigger group I used in my Tactical NG-SMG-1. The original concept was created by yuras12, but I made my own version and made it so the system would function correctly with higher rotation speeds. This trigger group is based on the XM-16A2 or M-16A2 trigger group, with modifications to allow better performance in Algodoo. If you wish, you can utilize this design, but I would ask you give credit to Yuras12 for the initial concept and myself for the finished, functioning product. The system is NOT perfect. It will occasionally skip a tooth and fire a 2-round burst instead of 3. It sometimes also fires 4 or 5 rounds. That is rare, though. In most cases, it will fire only one or two rounds as a result of the toothed-camming wheel being in the wrong position as a result of previous firing in another mode or releasing the trigger too early at 1 or 2 rounds being fired. The next pull of the trigger will complete the cycle, with the next cycle being set up for three rounds.
