    K series valve and 12g stuck in lower tube

    I am not sure what happened but the 12g the valve stem, and the part of the valve that has the face seal in stuck inside the lower tube of my kp2. I can hear and feel the valve parts move around in the tube but for some reason it won't slide out it seems to hit something and just stop. The Oring that sits on the valve has been removed as well. I was trying to hit the back of the 12g to get the valve parts to come out but it seems like nothing is moving and I don't have pliers long and small enough to fit in the tube to grab the stem

    That looks like the end of the 12ie to me, not the chamber plug.

    The face seal turns into mush and sticks everything together. Also the stem gets stuck in the 12 gram neck cause the mush seal no longer take up the space.

      You know the 12 gram HAS to go out of the front right?

      In all cases you need a trusty wood dowel.

      If thats the valve and chamber plug hit it from the front. I have best luck holding the dowel and marker together, and striking the dowel end on the ground.


      Gently take a wood dowel and insert it from the rear of the body. Then tap the 12ie free.

      There is a soldered collar it won't get past.

          After banging on the 12g from the valve side I was able to dislodge it. What happened was the pierce pin was pushed so far into the 12g they were pretty much stuck together as one. Embarrassingly this happened because I aired it up with a constant air adapter forgetting I had a spent 12g in the gun already from the last time I used it. So I guess the pressure pushed the 12g so hard into the pierce pin they got stuck together. Very silly and stressful mistake on my part. Luckily everything works fine.
