Hw35 Leather or synthetic piston seal ?

[les allam]

The last 35 I bought from Micky2 on here was a .177" synthetic sealed gun and ran very nicely at just below 12ftlbs, Les.

So as long as your cylinder is sound changing to a synthetic sealed piston should keep it running nicely --- and having a little bit more swept volume gives a little more wriggle room for tuning.



All the best Mick

Ok Mick, that sounds like a worth while upgrade.
If I can take you up on your kind offer regarding the knibbs piston that would be great.
