ok i solved the problem, i changed two of te lpr o-rings, changed every single o-ring on the bolt also, except for 3 of them, AND lubed them all. Boy this took me 3-5 hrs to do. It was because i had my hyper2 reg out all the way, so when i tried to dryfire, it blew almost all of my o-rings lol. This was a user error, so i still love my dm4. Now i could play tomrrow without worries.
