So finally got to playing with the ULE mag I picked up like a year and half ago 
and it is being a little in consistent to say the least. Executing a proper crono (hold trigger, shoot quick) the first shot is ~300fps then the next two drop to ~275. I wait a little bit and its same story first shot I crono is high then it drops about 20 fps. I switched out the elbow at the valve after the game a find a sizable piece of ring i the intake of the x-valve. I am now thinking of doing a full tear down of the valve to see what else I find. Any recommendations for a full overhaul of a x-valve people would like to share? Tools on hand, what too look for what not to sweat?
Thanks.
