I also had Kris build up my FN30. He did an excellent job. Not only does he reassemble the gun, but he arsenal reconditions it also. He turned my fair condition parts kit into a very good condition gun, wow! The only small complaint I would have is the trigger pull is very stiff. I cut the sear spring down and that helped a lot. Kris told me he is making replacement sear springs and that should be the answer. I am going to experiment with modifying the cartridge stops to convert to 8mm. I will post my results on the board.
