I figured I love the phantom barrel. So, I rethreaded an 8" phantom barrel and now use a .679 insert.
Then the stock pump handle was about the same length as the barrel and I was nearly shooting my fingers. So, I made a pump handle that is about .750 shorter. I then shortened the pump rod about 1" and continued the threads along the larger diameter section.
