Setup:
“Custom RT ULE” new from AGD. This has the ULT trigger and X-Valve.
Ninja 68ci/4500 tank at 850 PSI.
Macroline and 2 90 degree fittings.
I am stumped. I ordered the new automag directly from AGD. When it arrived, I aired it up and fired a few shots. No paintballs, but it seemed to work fine. I put a squeegee in the breech and found that the Level 10 bolt worked great. There was a leak which I was able to fix by cleaning and oiling the regulator pin o-rings.
Then today I attempt to chronograph the gun. No luck. It won't fire a paintball. There is enough presure and airflow to fire a paintball, but the Level 10 “trips” against the paintball in the breech and the bolt sticks about 1/3 of the way into the breech, venting air. I can move the bolt back into place with my finger, which stops the leak. The paintball is fully in the breech when this happens. The gun cycles fine without paintballs, but paintballs make the Level 10 trip without reason. Adjusting the velocity does not change anything. I started from all the way off, where the gun will not fire, and gradually increased the pressure until the gun cycles. Same symptoms.
I diagnosed this as a problem with the Level 10.
I had done some reading and research on the Level 10, and the instructions for tuning the Level 10 seem simple enough. I have gone through the process a few times now, and my gun does not behave as the instructions suggest. Without any shims, the Level 10 has a tendency to stick forward as I previously described. The difference between zero shims and several shims is not much. With 3 shims the bolt is less likely to stick forward when the Level 10 trips, but otherwise it is clearly not operating correctly.
I understand that this could be a problem with the ULT, but I have no idea how to determine that.
When I ordered the automag and selected the ULT trigger, I assumed they would include the stock on/off assembly that originally comes with the gun. They did not. I am stuck with the ULT for the time being.
Before you ask, yes, I oiled, it. I can look inside and everything is well lubricated.
Thank you all very much for your time.
EDIT: I have a "Reactor on/off" that came with my other automag, but I don't think it is compatible with the X-Valve.
