I remade the trigger, still using the same wheel/sear though. I am going to finish it this weekend hopefully, still have to fine tune it and figure out how I am going to mount it inside the receiver.
I also came up with a new idea to limit the forward travel of the band with a U-Bolt cut in half and welded to the frame. I got a free U-bolt at work today, left over from a conduit run that I finished. I want this so I can attach an arrow rest (removable) and also attach a front sight to the crossbow. I am going to come up with some kind of rear peep sight, or I may just use an ar15 rear sight.
