Level 7, Minimag valve, changed O-rings in power tube and on/off with proper O-rings from a kit.

When I disassembled the power tube I discovered an O-ring behind the spacer but also one in front of the spacer. There is a third one on the tip. When I reassembled I left out the O-ring in front of the spacer, that is the one closest to the brass tip but not on it. I don't think this one is supposed to be there. Ran oil through and oiled everything before reassembly.

The original problem was gassing down the barrel. Now ocassionally the bolt does not reset. Its not gassing down the barrel. The sear is good. The spring was replaced after I discovered the bolt not resetting. The spring is gold coloured. The problem persists with or with out the Noxx twist/cocker adapter installed.

Is the spacer ( .220 ) to short? I am at a loss to figure this one out. I havent had to do any maintenance on any of my mags for a couple of years. What am I forgetting?

Any help is greatly appreciated.

New main spring needed most likely. They wear out after a while

That is a fairly long spacer for not resetting. You can't be too far off.

Do you have your rail bushing in place? You would have to be pushing your valve forward during assembly, but its usually worth asking.

Make sure your body washer where the bolt passes through is clean and clear. Old mags can have some nasty build-up there.

I was assuming that the replacement spring was new, but that would be a good point otherwise.

Does the body have the stock finish on it?
Is the power tube tip coming loose after firing it?

Hey Paul, my phone is dead. Got your message but I can't call back.

It's definitely a strange issue, considering the fact that it shot fine when I saw it a couple weeks ago.

I'm kind of stumped...what happens if you put the oring back in there with the spacer?

The body is stock.
Yes the tip is coming loose or was I ran out of air.

Level 7 mags don't use the Gold Spring... that's from Level X installations

Try replacing the o-ring on the tip if you haven't already. I was having similar issues with bolt stick and double firing on a mag last week pulling my hair out trying to swap out every part to trouble shoot before I ran out of air. The power tube tip not staying tight was one issue I ran into swapping out different spacers. My issue in the end was the body was refinished and polished where it met the rail and the tolerances were out of whack.

The drag on the bolt causes it to stick more often. Its not leaking so the second o-ring isnt needed.

I will try another spring. I have a bunch but the gold one is the one that has always been on that valve. Previous owner must have put it there.

I have replaced the tip O-ring and it hasnt moved. The first one was very dried out. I think the issue here is the tension on the frame screws. I loosen it up a bit and it seems good. I'm handing it back to a friend who wants to use it at a big game this weekend. I'm hoping it will be alright. I will advise him to take a backup marker.

Thanks everyone.
