? about Lvl x when it is factory installed.

[The Fiat]

How much adjustment is needed on a gun w/ Lvl 10 that comes from the factory with it stock?

I am buying a mag w/ x-valve & Lvl 10 that is coming direct from AGD, and I was wondering if I'll hsve to mess around a lot with it.

Yes and no.

Depends on how busy they were. My Xmag's valve needed to be tweaked b/c the oring was WAY tight.

Gas it up, try shooting it. If it doesn't shoot, turn up velocity. If it doesn't shoot then, time to tweak the setup.

AGD sets up the valves VERY tight from the factory. You will notice velocity fluctuations on a brand new gun for awhile. Feed it some oil and get out and shoot it a bunch. The best thing to do is just put some use on it and then after about a case or two, take out the valve and check the fit of the LX o-ring. Slide the bolt back and forth on the powertube and if it feels like it's really "sticky", the o-ring is too tight. Take out the carrier and use the SAME o-ring in the carrier one half size larger. So if a 1.0 is in there now, go to a 1.5.

Try the "fit" test again. Keep increasing the size of the carrier until it starts to leak down the barrel and then go back one carrier.
