A leak down the barrel is normally one of three things, the front o-ring on the ram sleeve, the cup seal (little round yellowish disk between the ram sleeve face and the poppet), or the poppet o-ring.
Keep in mind that just because the o-ring looks okay, it could still be bad. I would just go ahead and replace the poppet o-ring and the ram sleeve o-rings (might as well do all of them if you have the ram sleeve out anyway). Before you put things back together, make sure you are lightly greasing the replacement o-rings with a quality paintball grease (preferably Dow-55).
If that doesn't fix the leak, then flip the cupseal around (often this will get it to seal). If that still doesn't work, replace the cup seal all together. If that still doesn't work, repleace and grease ALL of your o-rings. If that still doesn't work send me your marker and I'll get it working.
I find that 99% of the time a leak related problem can be solved by tearing down a marker and replacing and greasing all o-rings.
Also ignore the guy above who said it's most likely the solenoid (without even hearing your problem). This doesn't sound like a solenoid problem at all. He is just trying to get you to sell him your NME for cheap.
