    don't lighten the piston unless you are reducing the stroke...

    TBH the best bang for buck tune for these is to shorten the stroke a bit.. 8-10mm is plenty.
    Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.

    Seller on bay of fleas is also offering a 25mm reduced cylinder conversion - but it was just a bit too rich for my current budget, and given how smooth it was out of the box if reducing the power slightly brings that back I'll be happy

    Will never be as dead as my reduced/sleeveless TX's and Prosport.... so its never say never on cylinder reduction, but just not right now

    Halinfax on airgunforums does this, he did my hatsan piston, supplied a spare delrin ring too.


    He also lightened (drilled) the piston & threaded the barrel for a silencer
