OK, I will bit. I can't get mine apart to add shims. :/ I've pushed the center pin down so the bottom pin can be grasped; but the sticking-out pin doesn't come all the way out, and once at that point, I can't figure out how to get the on/off top off to add shims.

Help?

Nevermind; more force was required. Now up and running, all 5 shims in, all told, no shootdown or runaway. here's my question; do we want MOER or LESS shim action here?

[Jerhew]

it appears that the more shims you have(without it going into runaway or doubling) the lower the likelyhood of you short stroking...
so i'd say more is better

You shouldn't need more shims

there's that word again
"shouldn't"
pfft

well if it's still not working you can use level 10 shims...
just remember that they're twice as thick

serious issue with ULE

OK guys, I would definitely appreciate some help on this: I gas my gun up, test fire once or twice, and then the bolt continuously does not reset fully. I have to manually put my finger in the breech and reset the bolt. What is going on? It didn't do it until I put in the ULE. The trigger feels totally limp and the sear pin is not being pushed out at all by the xvalve on one or two occassions as well. I run a Crossfire 68/3000 preset and didn't have this issue before, it was a totally nuisance today at Boston Paintball, I sat out a few games because it wasn't working. I added shims to the point it went into runaway if I sweetspotted.

Any thoughts into what could be causing this to not gas up in the first place or after a few fast shots not let the sear reset for another?

[Jerhew]

hrm
is it well lubed?

[QUINCYMASSGUY]

lubed

Yeah, I put some oil in it, I also was getting borderline runaway (random doubleshots) just now so I took a few shims out. I wouldn't mind it being a little closer between shot and refill but it is also still sometimes not resetting right, mostly when I put my finger in the breech and shoot (in my apartment). When I have the issue on gas-up, it's almost like no air has filled the valve, then sometimes just "click" and it locks in. The on/off is lubed. I just don't get it and it is really making it unreliable to use.

[Jerhew]

just seems more like the kind of thing that happened when i was breaking in my level 10
did you try turning your velocity up?

[QUINCYMASSGUY]

lvl10

Level 10 should be fine, shooting 280 pretty steady, removed one shim because I was having an issue where if you put a little weight on the trigger it would start leaking, and it has no leaking down the barrel. I'm somewhat convinced it has something to do with the on/off or sear as it also shoots often when I gas it up. It sometimes lets the bolt move forward and stay there venting when I gas up and then if I reset it or let it fire, it's fine, I don't have a clue what's up.

[Jerhew]

well all i can say is
check and double check everything
check the sear and bolt lip for wear
make sure the on/off pin isn't bent and moves freely
then i'd say install your stock on/off just to make certain the ult on/off is the problem
oh ya make sure you have enough air in your tank
i dont know how many times my gun has started acting funny and worried me for a second just to see i only has 500 psi in my tank

[QUINCYMASSGUY]

good idea

Good idea, I know it's not the air, I was gassed up and filled it and still had the issue, and the tank hasn't ever given me issues, but switching back to the normal one could be a clue. Thanks!

[speeddemon]

I think I though of a reason why the LX bolts are getting stuck. It happened with mine when I tried it on my dads classic valve, but I didn't really worry about it since my X-valve is coming. I bet the kick back of the new on-off pin isn't enough to get the sear back on the bolt, and the reason it does it when you short stroke, is because there is even less kickback. I don't think the shims (in the level 10) would have anything to do with it getting stuck as long as it was set up right in the first place. They control the venting point if it pinches a ball, and when the bolt is getting stuck with the ULT, there isn't any air to vent.

Try upping the tank pressure if you have an adjustable reg. That is if adding more shims doesnt work.


This is all speculation, and I really don't have much way to test it since I don't have a valve right now, but I figured Id try and help somehow.

tank

I have a set pressure tank so I can't adjust it. I was always under the impression Mags work fine with a Crossfire tank but that could be the case that 800 isn't enough. If it is, I wasted my money because this problem definitely caused my gun to go down and I don't have faith in it to work right now.

[BlackVCG]

The only times I have had a problem with the bolt not reseting is when my air pressure is too low. I would have the output of the tank checked to make sure that is good. Do you have an intellifeed setup and what kind of trigger frame are you using?
