Finally got the Epic working again...
Alright. It's been a long, hard journey. But it works.
So I had all kinds of problems with my Epic, which normally never happens. I believe it's due to my tinkering. I tend to tinker.
However, after finally figuring out how to run a 400 PSI output tank on it without the regulator constantly releasing air pressure and figuring out why it kept leaking profusely down the barrel, I am entirely satisfied with my Epic.
It's been out of commission for about two years now. I just quit messing with it after a while. Surprisingly, I never got impatient, so nothing got scratched. It works great now, and I'm happy.
Anyway, if anyone else has been having trouble with their Epic leaking down the barrel, PM me and I can help you out.
