I have had a S6 for over a year and a half now and have had the same reoccurring problem. When I pull the trigger and shoot a ball the valve sticks open and bleeds air down the barrel until I cock the gun again. This has been happening off and on for over a year. I have rebuild the reg, set the pressure. Replaced all o rings. Can you please help me diagnose the possible causes for this?
Thank you in advance!!
