ULT turned into bullet

[djslik]

Well i was dry firing my ult custom which i just got in the mail using my friends flatline tank set to about 1000 psi. The gun would shoot fine and then it wouldn't reset. I would have to push the bolt back in and hear the click sound for it to shoot again. My friend says try a different level 10 spring so i put in the raw colored one. We turn off the tank and the remove the valve. The gun sounds like it has a lot of air still inside of it so we shoot it until the gas runs out, but I notice the ult trigger won't allow the valve to be pulled out because it has come out a little and is getting stuck on either the body or the rail so i take of the trigger frame screw. I thought that was weird and I put the new spring on like I intended. Well we gas up the gun and nothing happens, literally and i think it was because maybe i had to turn the velocity up, but i only thought of that like today, anywayz, we turn off the gun again and had the same problems as before, but this time when i got the valve loose the ult trigger assembly shot out like a freakin bullet. It went all the way across the room and bounced off the wall, almost hit me in the stomach on the way out. I want to know why there was so much pressure in the valve and how to correct this. We shot the gun until it wouldn't shoot anymore but when we wiggled the valve all kinds of air was coming out, i mean a lot and the tank was definitely off we checked twice. Is there a way to degas the gun so i don't kill myself and what is wrong with my gun...sorry for the long post but i need to know before i go and play.

Use a quick disconnect, slide check or pro-connect to bleed the air from the line.

The gun will retain pressure inside it because that's how a regulator works. It'll have enough in it to shoot the on/off pin but not enough to shoot the gun.

okay cool, i'll grab one on tuesday...and the bolt reset problem, is that only due to the torque difference between the field strip screw and the trigger frame screw, or is there something else to look for?

[Bad_Dog]

been der done dat... but It never shot out of the valve like that... it usually just hits the rail on the way out...? how can you pull the valve out fast enough to get it to fly out like that?

[djslik]

well what happened was i used a pen to push the pin back in through the hole in the bottom of the rail and when i took off the trigger frame screw the body loosened up. After that the valve came out real easy but as soon as i rotated the valve past the rail it shot out really fast, scared the crap outta me.

oooOooOoOooooo

Mine has done that as well and hit me directly in the face. It gave me a 1 inch gash in my forhead.
This allso happened at a tourney last moth and the valve hit the guy in the eye. He was taken to hospital with bleeding under his retina but no permanent damaged was caused.

A quick disconnect will not solve this problem. The ULT holds a partial charge against the oring in the Level 10.

You must completlty degass the marker, remove the rear field stip screw and carefully slide out the valve and bolt with the ULT facing towards the ground ( or better still with a towel over it). Gently shake the marker forward so that the bolt can move forward and discharge the trapped air. Then the valve can be removed safetly.

I posted this problem a few months back on BlackVCG's ULT Thread

[djslik]

wow...yea...i admit...i didn't read all of BlackVCG's thread...so the only way to prevent this problem is to actually put a towel around the valve, well...if that's the only way i'll do it just so i don't hurt myself.

hey man... i see that you wanted to know the original problem with your marker... thats the answer that i have for you..... its that your 2 frame screws are at different tensions.... use the link in my sig to read up on it.... but heres the long and short of it....oh yeah.... its got nothing to do with lvl10 springs... i wish ppl wouldnt suspect lvl10 on this problem... what you need to do is put the marker together and gas up.... fire untill the bolt doesnt lock up.... then tighten the field strip screw with an allen wrench until you hear the bolt lock in... at that point you'll know that you have the 2 frame screws at equal tension... what was happenin?.... well the lightweight aluminum ULE bodies get kinda twisted cause they arent super rigid.... that twist causes an intollerance that forces the bolt to jam in the breech near where it should be locking up.... hope that helps.... good luck ---> once again read that link in my sig for more RTP ULE info.....

i read your post and i was fiddling around with the field strip screw when it happened, but i misunderstood and i thought i had to loosen it...and it wasn't doing anything...thanks for clearing up the confusion...i'll try that today...i think it should work

I clocked myself in the neck with an on/off once. Hurt like hell, but no permanant damage

It's something the level 10 does. There's enough pressure to reset the pin, but not the actual bolt. So the air just sits. It'll happen regardless of the ULT or stock pin. This is a well documented occurence with the Level 10 system. You use the QD on your air line and it'll completely degas the gun.

A quick disconnect will not solve this problem. The ULT holds a partial charge against the oring in the Level 10.

I've got a Pro-connect on my X-Valve, and it does a great job of degassing the vavle when/if I need to take it out of the body.

I had completly degassed the marker and removed all the air hose lines.
There was nothing attached to the back of the valve.
I had just the trigger frame, rail, body & valve together.
There was still enough pressure between the ULT on/off & level 10 to blast the valve into my head.
