So i picked up a used sniper that had the auto trigger removed, but all the take off parts came with it. I reinstalled all the auto trigger stuff and got it working, but i noticed after shooting like 30 balls the cocking arm rotates and the pin rotates out of the auto trigger arm? How do i fix this? Do i need to remove the pump handle and make sure the cocking arms are equal length and loc tite them?
Ive already had to take the pump handle off and use sand paper to clean the bore of the pump as it was sticking badly, full of gunk and putting wear on the pump guide. Also it looks like the pump guide allen on the front is stripped out, is this going to be ok or do i need to get in there for anything?
