valve o ring?

[smallerfreeze]

I would pull the powertube off and inspect it before I put air through it.

i will

i will

Do you know how/have the proper tools to torque the powertube back on correctly?

OP,

I have to say that you are having some strange, chronic luck with dubiously modified valves.

You'll definitely want the correct o-ring first (think it is 1mm x 20.5 [ID]), and to make sure the threading isn't damaged in any way.


But as far as you are concerned, in its current configuration I wonder how well (or if) it will function.

First, with the power tube pushed forward the bolt will likely now sit into the breech. It may not be a lot, but it may inhibit feeding.

Second, and much more importantly, there may be an issue with proper sear lockup, given the bolt is now forward of where it was designed to be, and may behave like a pump mag, except that you cannot recock it.

None of this will be much problem if you can get everything sorted out with a new o-ring, but again, I'm bothered that someone just sold it like this.

To your question about it being this way owing to possibly sitting for a decade, no, for two reasons: (1) the original o-rings are red, and (2) the practice of cutting these open and using efficiency inserts didn't really come about until about five years ago.

Could be the powertube tip was cut off on a lathe and they cut to wide and just stuck an oring on to fill the gap. But the tip is likely screwed all the way down.

Hopefully you are correct.

But having lived on planet for a while and seen some of the inhabitants and their ways, I assume nothing.

1hga15V.jpgfhQG4IE.jpgfhQG4IE.jpg ... the power tube was screwed as far down on the o-ring as it could go and wouldnt budge with hand strength.... i took off the o ring and the powertube was not screwed down all the way

HRBh6YS.jpg46CwQw2.jpg you can see in the second picture that the o-ring was not letting the powertube thread all the way down

Is this screwed in all the way?

correct that is screwed down all the way... the o ring was not allowing that to happen.. but it wasnt moving no matter how hard i tried to unscrew it... that last picture i posted is of it right after the o ring was pulled

Looks like they just cut a little deep to remove the powertube tip, install the correct oring and see if it seals.

thats the plan, thanks a million for the tech support .. so what exactly is the KKM? id like to buy a few orings that will hopefully work
