So, my Minimag RT madness continues (following up from:

I rebuilt the valve using a AGD kit (no eBay shiznit!), and while I was waiting for the parts, had Luke set the valve up for a ULT assy. Forward to today: I rebuilt the valve using some of the parts out of the kit (didn't need to rebuild the new ULT). BUT, when I dry fire it.... I get a putt-putt-putt weak sound. It's just meh. I tried a paintball in it, and I probably could have caught it in midair.

SO... I'm not getting the velocity I would expect, even with it turned all the way in... what am I looking for? What did I miss?
