    Stock 0.171".... now 0.183".... Probably not enough smaller to do what I need, but Dan thinks he might have one so I'll get him to send it when I get a backup complete valve (which he has in stock - $50).... He seems to have a pretty good supply of spares for the Hatsans, which is great to see.... If Fastenal would ever ship my Teflon rod I could probably just make one from that and eliminate the two tiny O-rings.... The stock TP has a 1mm section O-ring riding in a shoulder on each end to seal it.... Nice attention to detail.... I could always duplicate the factory setup with a smaller hole, of course....

    sorry to reply to an old thread... but what is your turn measurement on the hammer spring preload screw? Is it a 180 or 360 degree turn?
