Problem Solved: Tac 1 going full auto

Okay so took my tac one to the field today and something is wrong.

Marker airs up fine. Pull the trigger and the gun goes full auto. Let off the trigger and either it is stuck in full auto or it stops and will go full auto again if the trigger is pulled. No other leaks are present, my orings look okay throughout the marker, and the sear and bolt both look okay. Not really sure where to start.

I haven't adjusted anything since the last time I played a couple months ago with it, and it performed beautifully then. I need this fixed by Aug. 6th, so I need help as quickly as possible.

Thanks

1. Oil...
2. More Oil...
3. Ck the 2 top orings in your on/off. Just replace the center one (smaller one of the 2).
4. If you have a ULT. Remove a shim and try it out. Keep removing them till it stops.
5. Might have something wrong with your sear and/or bolt. Ck for wear.

Trying to think of what else might be doing it. I'll post later.

I have a ULT installed. Had 4 shims in it then cut it down to 2, but didnt help. Ill post a pic of my sear and bolt sometime tomorrow to get an opinion on if they are worn or not. They honestly look fine to me. I looked at my orings and they seemed fine. Already lubed everything up really well. I just don't know how one day it works fine and I don't touch it for a month or so and its messed up.

Check the main spring... it should be longer than the bolt when together. If it's weak it wont push the bolt all the way up onto the sear.

Check for proper trigger gap.
1/16" from back of trigger to tip of trigger rod with marker gaSsed up and safety on.

Also check to make sure your rail bushing is still in place.

gold and silver springs give me full auto. The red spring is too stiff and doesn't allow the bolt to travel forward.

That seems like a likely evil culprit

Okay, so I've checked the rail bushing and its still there. Here's a pic off my cell of the sear, and the bolt looks like it is in perfect condition.

Okay, so I noticed something new. It appears that the center of my bolt bumper is torn out about 95% of the way. You can't tell unless you try to take it off, but its possible that it separates and then the bolt can't return all the way back and the sear is unable to catch it. I'm really hoping this is the issue.

Also, during my trouble shooting this rubber black piece that is supposed to be glued to the front of the bolt came off. What should I use to glue it back on? Is it necessary to have in there?

Automag 101.

If you hold the trigger and the marker leaks down the barrel (hisses, puffs, goes full auto), you have a malfunctioning on/off assembly.

By your initial post, your problem is there. This can be caused by:
Leaking on/off top o-ring.
Too many shims in a ULT.
Missing rail bushing.
Improper gap between trigger rod and back of trigger.
No oil.

The above reasons are 99% likely to be your problem.
