this is my first mag:
x valve
lvx
ult
right feed steel mainbody
preset (high output) crossfire 68/3000
i am using the shortesd lvx spring, three spacers, the carrier with one line and one dot (not sure of the number designation), a brand new tight fitting o ring, and i have the flat white backing washer at the very back of the power tube. the ult has six spacers. everything is well oiled. the carrier/o ring combination is the loosest fit that doesn't leak. my velocity is ~ 2.5 turns from bottomin out
now that you know that... when i pull the trigger, occasionally the bolt will proceed halfway across the feed neck opening and vent air. this usually happens when i try to walk the trigger, or in testing, when i pull the trigger and then pull it again very slowly. all of this is without paint, when i cycle the marker with paint it double feeds and breaks paint in the barrel. please tell me what is going on.
i figure, if anyone can help, it's you. as i saw in another thread, you are the manual.
sorry for the phone book. thanks in advance.
p.s. i bought the marker on Ebay, then bought a very slightly used factory assembled tac one, i decided that i didn't like the look of it and took the x valve (ult pre installed) and put it into my other mag.
