Maybe this is a little late, but just wanted to weigh in since I have been mentioned.
I am the "SAM" that MagRippa214 mentioned, not AngelBoy, and let me say that despite the things he's said, I do not share his opinion on the Epic.
Although it has not worked for me yet, I have recently shipped my marker back to the factory for repair (the exhaust valve was leaking bad), and I'm looking forward to getting back a working marker.
From the little I saw of my Epic, it was loud, but very small and light; the trigger wasn't very nice, but its a mech gun after all and seemed accurate despite the constant leak while I was shooting it.
The time MagRippa mentioned when it "chopped", I was just pissed at the leak and my broken N2 tank, and so I screwed in a CO2 tank in freezing weather and shortstroked the gun about a million times in a row as fast as I could. By the end, I was shooting liquid paint like a squirtgun. When I opened the hopper, almost every ball I had had inside was broken and it was paint soup.
My theory about this incident is that shortstroking the gun while sucking liquid CO2 caused the trapdoor to not close all the way, and the massive blowback broke the balls in my hopper. Incidentally, I also experienced the worst shootdown I'd ever seen, but I can blame this on the shortstroking and CO2 also.
In short, mea culpa, not the gun's fault.
oh, BTW, about the alien - I sincerely hope that Jack isn't forced to shut down his operation, the alien looks like one of the coolest markers i've seen in a long time.
Jack's theory is that since most of his marker's design is substantially different from the Epic's, and the trapdoor seals from the side instead of inline, he's in the clear.
Unfortunately, the language of Jim's patent specifies a marker which uses a "flat partition" to seal the breech - and if that's to be taken literally, he's got Jack there.
If Jim shuts Jack down, his E-Epic better make it damn worth it...
