The ptfe liner I made, you can buy sheets of it off for a couple of quid,I wrapped it around the 77 spring and cut to width, measure length of piston internally and add 10mm, then cut triangles out of one end for it to fit around the latch rod, job done, take that piston weight out, replace with a top hat.
Weighed piston @ 367g with weight in it, 345 without, could lose some weight on it really, my 77 runs a 200g
is it still the 80 piston inside ie 30mm

do you have a picture of the new cocking link please
