Hi ! I have a problem with Dye DAM starts leaking somewhere near the trigger as the velocity goes up above 240 fps. I understand that it`s a common problem, but can`t get accurate info about how to repair it. Is it the problem just with the solenoid (if yes, will cleaning and re-lubing will help?) or it`s a problem with bolt assembly? P.S. Leak started after a year of using it.
