So my friend's dboys scar stopped working a while back, and he left it at my place for me to try and fix. The original problem was the trigger switch prongs, I guess you could say were separated so that the middle one wouldn't connect them. So I bent them back into place, tested it with the volt meter, and it worked. There must be another problem though, cuz when all put back together it won't cycle. I believe it has something to do with the tappet plate though, cuz the loading nozzle stays out so it's almost impossible to put the lower back into the upper. I've attached some pics, any insight would be great.
