New Tac-One quickly becoming a headache

[grominou69]

Mine came stock with the smallest spring. Interesting...

one thing you should know is that every marker that comes out of the factory with level 10 installed on it is factory tuned to ensure that it works properly before sending it to the costumer ....
but the settings (carrier size , spring length ) are changing after break in (about 10 cases of paint shot thru the mag) so you have to readjust it ...
that's why i suggested you to find someone that can explain you how to tune it yourself ....
it's so easy that you don't have to be an engineer or have special knowledge in pneumatics to "understand" a mag ....
hope rogue will be able to find your problem ...
you must know that every mag problem is never something complicated or expensive .... always a little oring or just a few drops of oil

Again, thanks for the kind words. Yes, I understand things like O-rings and such need to wear-in a little bit. I've already gone that far and have no problems with the basics like that. It is understanding what this gun is telling me that appears to be the problem.

RogueFactor called me last night and we went through a number of things I wouldn't have thought about (like looking at the sear assembly for signs of fractures). We ended up getting the gun to work, but it was too dark to chrono and make final adjustments. I also used up all the air in my adjustable tank.

This morning I got up early before work in order to satisfy myself and chrono the gun. I connected my fixed tank up heard the click that tells me there's enough to run the gun, then pulled the trigger. Same ol' problem all over again -- gun just runs away until I let go of the trigger. This is not because of trigger-bounce -- I had the trigger firmly against the frame.

Rogue' suggested dropping the RT on/off back into the gun. I did that. No change. Just on a whim I gave the velocity adjuster a little twist (about 1/8 turn up, then back to where I started). For no reason I can explain, the gun is back to firing single shots. Everything is OK now right?

Wrong: I left the gun to sit for a couple hours completely ungassed. When I tried to fire again back comes the ol' runaway. This has been the pattern I've been experiencing since I got the gun -- factory tuning or not. I'd play for a couple rounds and everything is fine, then after a pause between rounds everything goes whacky.

Current setup:
Level 10: 2 shims, 1.0 carrier -- no leaks because of this
RT on/off assembly

I'm completely lost here. I'm not mad, the situation is kinda funny given my career (software tester). I would like to know what runaway on a 'mag means so I can fix it and get on with paintballing...

Gun is heading back to AGD for repair or refund.

I'm not mad, just a little disapointed. RogueFactor couldn't figure it out, so I might as well send it back to AGD and keep them accountable.

If by rapid fire you mean full auto check the reg seat.

If the reg seat oring sticks on the reg pin you will get full auto.

Unscrew the reg halfs and see if the reg seatin stuck in the reg or sliding on the reg pin.

Either way put a little grease on your reg pin and reasemble and test it.

This could also be a cause of your lack of consistency.

Thanks for the response, JimBud. I do appreciate it. I will add this to my list of symptoms with possible solutions. I tend to agree: This seems like a regulator problem, but I'm not experienced enough to know how to fix it permanently.

There is also the problem that I don't know which part of the valve is the regulator seat. The only diagram I have has just numbers for the parts with no cross-reference. I had used a few drops of "Autolube" on all parts every time I took the gun apart. I assume this is the recommended lubricant...

Second, the gun is on its way to AGD already.

As an aside: Assuming I ever needed grease (like for the back half of the regulator) what kind should I use? I noticed in the back-half the grease is silvery for the springs back there...

Here is a link to an exploded view ov your valve.

You want the retro valve.

The reg pin and reg seat oring is shown.

Any synthetic grease should do on the reg pin.

Update:

Got my Tac-One working perfectly.

Turns out there was an o-ring misplaced -- the one that is supposed to go in the face of the rear-half of the regulator body. Instead, it was embedded in the the reg-seat holder (the side with the cross-wise grooves) and preventing it from moving freely. After placing it in its correct location, there hasn't been a hitch in the gun's operation and consistency is way up.

Thanks to all who gave me encouraging words and suggestions.

Whew, I'm glad that's cleared up. I was about to just make you sell the thing to me at a discount and then turn around and tell you there was nothing wrong with it!!

Misplaced o-rings are impossible to diagnose over the phone

Hey, no problem Rogue' you did the best you could. LIke someone else said, it's usually the simple things and besides: I didn't know what to look for, and your assistance really helped me understand how the whole mechanism worked.

To the rest of you our ther: Anyone who needs help should seek out RogueFactor's assistance.
