so i took the gun apart to clean and tech the reg and as i tried to put all the parts together again, the autotrigger would not stay put on the frame but rather come off rather easily if pull on it. I took it to the local paintball store from which i bought the gun and they are stumped too. I dont remember any forgetting any pieces nor losing any piece. There is nothing holding down the auto trigger. In the older ccm s6 markers, there used to be screw on the pump rod that you could use to take the auto trigger off and on but the newer design only has a metal part sticking out of the rod.
