Phantom CCI undercocking kit problem.
Hi fellow MCB,
I recently purchase a phantom with a CCI undercocking pump kit and every cock with air (HPA) the pump handle will stay in place, not finishing the complete "maneuver" of cocking back and then automatically pushing the pump handle back into the original position where I can just pump and then shoot. Anyone know how to fix this problem?

There should be a long spring that goes on the cocking rod, and a small partial white washer that keeps the spring from binding in the body. If the washer isn't there, its likely the spring has nothing to push against and is actually moving inside the body rather than providing return force.
If this is a problem only with HPA, that does seem a bit on the odd side..

also check to see if the pump rod is threaded all the way into the pump handle:
if yes, unscrew it until it is threaded with half of the threads showing.
check the alignment of the pump rod and the bolt--if these are off slightly it can cause binding.

In the world I see - you are stalking elk through the damp canyon forests around the ruins of Rockefeller Center. You'll wear leather clothes that will last you the rest of your life. You'll climb the wrist-thick kudzu vines that wrap the Sears Tower. And when you look down, you'll see tiny figures pounding corn, laying strips of venison on the empty car pool lane of some abandoned superhighway.

batteries not required
you don't need the return spring on the pump/bolt rod. a return spring does it's job as long as the pump handle/bolt returns to it's forward position through spring action. having the spring on the UC kit pump guide is just fine if the spring has enough tension to return the bolt full forward.
or if you prefer to order one straight from CCI, i believe mike charges $2 for a return spring; however i might not be correct on that
