Took a Hatsan tactical semi in a trade ,was told it didn't cycle well with low power loads,no worries from what I've read there all like that.stripped it down for a cleaning and had to "persuade" the piston off the mag tube.bloody hell there was no way that was sliding .checked the inside of the piston and it has uneven rings that look to be left over from original man. Piston does not slide back over the tube-would have to be 'persuaded "on.o-ring is shot -looks to have been soaked in solvent ,but that's an easy fix for a Plumber,I have thousands.
-1 st thought was to take it to a buddy that's a mechanic and hone it out like a cylinder
anyone have one and has notice the same rings?
