Bolt Stick and ULT leak

[El Zilcho]

I have 4 shims in my ULT X-valve and am having an odd issue, in the course of a few hundred shots, I had the following issues, (not in this order)

If I pulled the trigger, the trigger rod would not return (if I pressed the rod back with an allen key it would leak a bit and then return)
If I pulled the trigger and held it, I would hear a leak from the on/off
Frequently the bolt would stick about .25 to .5 inches from the "returned" position (I think the trigger would stick when this occurred).

As I recall, these issues occurred in a relatively random sequence but, so many different issues were occurring that I can't say that they did not occur with some sort of predictability.

Are these issues symptoms of the same problem or are the a series of individual problems?

Thanks

Put a stock on/off in and retune the bolt. After you know the bolt is set right, tune your ULT. It could very well be how tight or loose you have your frame and thumb screw but checking those 2 areas will alleviate them

As mentioned, it could be a level 10 bolt issue. Remove all the shims from the level 10 bolt setup and make sure you are using the largest carrier that does not produce a leak with the oring you are using. Always use the same white carrier oring in each carrier that your try. Once that is done, then the ULT can be tuned properly.
