    The on-off pin remains inside of the small on-off top oring sealing the air passage until the sear can actually rotate forward. The sear can only rotate forward if the bolt is fully back in the reset position. Its not the pin that is causing leaking out the front in a pump mag anyway. Its the exposed vent hole. Normally there is residual pressure in the front chamber when the bolt resets. If the vent hole is exposed, that air is allowed to escape, so its wasted.

    The vent distance doesn't affect the operation of the level 10 for anti-chop. The vent distance only affects how far forward the bolt needs to be before it can vent the excess air out of the chamber so that the bolt spring can push it back to the reset position. In a pump mag, the wave spring would hold the bolt forward causing the vent hole to be permanently exposed which would allow it to vent all residual air out of the chamber.

    The level 10 will work for a pump mag as it normally does for any mag. The secret to get it to work without leaking air is too allow the carrier oring to sit far enough forward so that it is always in front of the vent hole. We don't need the vent hole for a pump mag since you are manually resetting the bolt anyway, so you don't need the spring force to be larger than the residual chamber pressure force. If you have a spare powertube tip, file it down to allow the carrier to sit farther forward. Flipping the carrier won't work, because the oring can be pushed forward out of the carrier.

    wow that makes alot of sense...especially about the flipping the carrier over...was thinking the powertube tip would keep the carrier oring in place

    if the power tube tip is filed down that wont cause any issues when switching back to a mech mag will it???

      Looking over athomas's post, yeah, I guess as long as the bolt is anywhere but home, all the extra meat on the front of the sear (always wondered what that was for) should prevent the on/off from opening up, so I guess that's fine.

      Hrm... I'm really just going to have to experiment with this.

      What are the specs for the wave spring and washer? I don't need the full pump kit to experiment with this. I assume Smalley made the wave spring; just need to know which one.

      Definitely not on the A-Team.

          Yes it will, which is why I mentioned that you should do it to a spare tip. You should maintain an unmodified tip for normal valve use. If you shave a 1/16" off the powertube tip, you can use a 1/16" shim to add it back, so you can use the same tip for both if you want.
          Except for the Automag in front, its usually the man behind the equipment that counts.
