Chplnstone did some great brass work on my Kp, he re-barreled, re-feedtube'd it added a spring feed, and he also did some other little things to it. The brass work is very clean, my kp shoots great, and right off the bat I was able to get about 45 good shots off a room temp 12 gram. Overall I am very pleased, and I would love to do some more buisness with him. His member title truely says it all, he really can bring back the dead.
