I would recommend buying another trigger box. The trigger box you have MAY be repairable, but unless you have the proper tools or trigger box experience, I would call it a lost cause. If you intended to use a higher FPS than stock FPS, then a new trigger box (upgraded not stock) would benefit you greatly.Yep their 2 pieces of plastic in bottom of box , I can see wereit supposed to mount and a jagged edge on trigger box.... So I need a new trigger box?
