Hello All, I am stumped-I am also phenom owner-worked great at West Point, then all of a sudden the gun starts going south.  I do all the marker work for my team as far as the 98's A-5's and X7's with 99.9% success rate on fixing them, but this Phenom thing has me shaking my head.  This past weekend I walked up the chrony, squeeze the trigger and I hear Pssssssssssst - puffffff- and nothing-No balls flying out.  I squeeze the trigger again, samething noise.  Bare in mind I am in semi auto mode at the chrony.  I squeeze the trigger one more time, and guess what, it was like cartoon-I hear POP! and the Cyclone feeder turns into a blender, and the only way can shut it off is by the check valve on my remote line. Needless to say a couple balls broke in the process.   Luckly I have my regular X7 that works like a charm to play the game for the day.  So during break time during the game-I talk to another individual that is having the same problem-Both him and I field strip the phenoms and found nothing.  Found no burs, no slices in the o'rings, the firing pin and brass fitting for the trigger was nice and tight.  To the human eye everything looked cherry. We took the whole flex valve apart and inspected every valve-o-ring-and any other moving parts and we could not find a single flaw.  I cleaned everything up and regrease with Dow33, put the valve back together-and tried it again-FAIL! Samething-Squeeze the trigger-and cyclone goes ape!
