Someone else posted a few weeks ago with a similar problem. His on/off pin was in backwards. Be sure the pin is oriented in the correct direction. The end with the grooves should be pointing down, away from the valve (I think), check the diagram on the valve. Also make sure the valve is well oiled. Good luck. -
My bad. I checked the other thread and the guy was having a problem with auto firing and his classic valve. But I suppose it wouldn't hurt to check the assembly.

hows about some oil have you put any of it in lately cause i know that can solve many problemsComment

The on/off is assembled in the correct way. I've just been tinkering with the gun a little and i've recreated the issue going on. It seems the bolt does not reset fully, and is causing the problem. If i stick a squigie in the barrel and push the bolt back, the gun functions ok untill the issue occurs again. It's some kind of bolt stick, but backwards in a way. The bolt does not reset fully and therefore the gun jams.
Any ideas? Because i'm clueless about the problem causing it.

If the trigger rod adjustment is good, I would try the feel the on/off pin movement in the base (classic on/off). The little teflon orings seem to get 'grabby' in their old age. I don't know if it is the shape or the surface that does it. Teflon tends to flow, and while that keeps the seal pressure low on a new oring, an old one will creep and start to present a wider and wider sealing surface, raising the friction.
I don't know the blend those orings are made of, but that is my suspicion.
**edit**
Try a new bolt spring or maybe a little longer power tube spacer?
No leaks?Comment

seriously it might just be that it lacks oil i had the same problem with my first mag i added oil and it shot great.

Oil is not the problem i think.. I oil all my mags before play, on/off, and some drops in the valve inlet. If the valve needs more oil, i'll have so soak it.
@ Spider_TW: I'll look into that first thing tomorrow... I'm sure the spring is ok, but the o-ring could be the problem. No leaks or the "sprinkler" sound.Comment

ok well i didnt read anything about you oiling it in your past posts so thats why i said it and no 1 to 2 drops is all you need of non patrolium based oil.Comment

Make sure that your powertube tip is screwed on all the way and that its o-ring is still on to prevent it from unscrewing.
That and possibly a new powertube o-ring should get you back out there.Comment

you might want to take off your barrel and try shooting without the barrel to see if you have any alignment issues .Comment

I think i solved the problem...
The bolt spring was about 1/8" shorter than a new one, it should still be ok but i replaced it just in case. The powertube o-ring was also replaced just in case, and the most likely cause of this bolt stick issue is the .220 spacer that came with this valve, and the bolt spring weakening. It's odd because the gun has worked very well before. I've replaced the spacer for a .225 and the issue seems gone. I'll be using this gun next weekend and i'll bring my spacer kit just in case (thank god i bought one!)
I love mags, but hate the problems with them because the solution is never that obvious... to me that is...
Thank you all for helping a fellow mag owner out!!

Well, at least you know it isn't a dead battery/crimped eye wire/blown noid that is giving you grief.
Glad to hear she is up and running!Comment

Heh, i never seem to have any luck with e-guns... Either the battery dies on me, or there's some other issue... This minimag was always a reliable marker the last time i used it extensively (8 months ago) but the last few times it had this weird issue. Because i never had to deal with something similar, i had no clue what to do... Well it just shows that i still have alot to learn about mags...

Cool. I'm glad you brought this up. I have a minimag valve in my co2 marker that is starting to catch the sear inconsistently, which you feel on the trigger pull. I replaced the bolt spring, which helped a little, but like yours, the old one wasn't badly worn.
I don't have a spacer kit, but I have some bronze springs.
I'm thinking about dropping a level 10 shim on top of the spacer (making a .230 spacer) to see what happens. Has anyone tried that?Comment
