Automag Problem, Plz Help!

[sodbrother]

I purchased 4 guns as a package deal and 2 of which were Automags. One of them I have not yet been able to fix. It is a Classic mag with a Retro Valve. When I screw the tank on the gun does the hisss, psst, psst and will not charge the valve. To get the gun working I have to remove the barrel and push on the bolt for 2 seconds. The gun powers up, the hiss,psst goes away and the on/off pin engages the trigger. At this point the gun works flawlessly until I remove the tnak. If I remove the tank without pressing the trigger I can screw the tank back in and it works fine. If I remove the tank and press the trigger (pusing the on/off pin in) then the problem repeats itself.

I purchased an O-ring kit from AGD and replaced every o-ring in the gun. I checked, double checked even triple checked that I have replaced all o-rings, and put everything together properly. I have owned several lvl 7 mags and consider myself fairly knowledgable on mags. This one has me stumped.

Did you replace the spring? That is what sounds like your problem might be.

[sodbrother]

Yes, I put in the new spring from the AGD Kit....

Does it have a level ten? Maybe you need a longer spring or something, i'm not sure what it could be if that's not it.

Sounds like the on/off o-rings are not lubed or seated correctly.

If you gas it after you seat the sear back and push on the bolt, I think your describing a power tube issue or that by pushing the bolt back more than it needs to seat you are either:
letting the sear set back on the bolt where it needs to hence the on/off can now seat down into the rail as it normally would or your fixing a bad seal somewhere in the are of the dump chamber (which I am not too familiar with unless I have a diagram in front of me)

I would like to say its the power tube,... but thats just a guess.

When I first got the gun I disassembled it and noticed the power tube O-ring was missing, upon further inspection I noticed half of the o-ring had been pressed down into the air chaimber, the other half was gone. I thought it was going to be a simple fix. After replacing it with a new one I had this problem arrise. I thought that maybe I had used the wrong size o-ring since I didnt have the original to compare to, so I took one out of a working lvl 7 mag that I have and this did not fix the problem.

I think the problem is in the on-off valve but I have gone over the on/off several times and cannot see any problems.

If your using the L7spacers use the next longest one.

[sodbrother]

If your using the L7spacers use the next longest one.

It has a .225 spacer in it now. I have a level 7 spacer kit and I tried a shorter spacer and a longer spacer, no luck with either one.

Looks like I might have to send it in to AGD

Are you using a stock AGD bolt? You might want to swap bolts. Also if it hasn't been used in awhile make shure the on/off is not sticking & lube it...

I am using a stock bolt and earlier today I swapped the bolt, spring, and bumper, and powertube o-ring from another working mag (lvl 7) with no luck.

I think the problem is in the on/off pin.... I have oiled it several times. I am not sure which o-ring to use. When I take out the on-off valve the O-ring that sits down in the valve is that suppose to be Neopreme (clear yellow) or the Teflon o-ring (hard, white)? I have tried both.....

Whats weird is that after I push on the bolt the gun pressures up and shoots perfectly until I remove the tank, press the trigger then try to air up the gun again.

hmmm that sounds like perhaps the rail bushing is gone on the trigger frame oops never mind i reread what you typed ..... try changing the sear with one that works im thinking the sear rod/plunger has been adjusted.

[athomas]

It definately sounds like an on-off problem.

A retro valve uses a urethane oring for the on-off top. The classic AIR valve uses a teflon oring. If you have an older retro valve it may have a recessed area that the small on-off oring fits into. A newer retro valve is flush on that surface and needs a larger oring to hold the small on-off oring in place, much like the on-off configuration of a classic valve.
