Well had a couple of hours today trying to get it back together did the milk bottle piston sleeve and ended up collapsing coils til I could get it back together ended up at 7 coils so 6 1/2 off and collapsed the cut and and ground it flat and still had to get a pal to come put all his weight on the cylinder into a rubber bung to get it in shoots horrible twangy stiff and just not nice at all didn't even put the scope back on I get know I'm not going to like it
