    Weihrauch: 25 or 26?

    Good morning gents,

    I would need your expertise; I have the opportunity to buy a HW77 in .177 with serial number: 1019349

    Am I correct in assuming that this rifle still features a 25mm piston?

    Many thanks and good weekend ahead!


    Best,
    Jonas

    Yes. If it hasn't been got at. Get a look/photo of open breech. In 25 mm the seal bore edge touches the inside dia. of comp. tube.

    Is it that important? (+~8% surface)
    I recon they are both good, just require different tunes
    We are not comparing 22 and 28 mm.

    Probably not for many users. Just a pity if someone buys one thinking it's original spec. then finds it's been cannibalised.

    Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.

    I have two of your kits in my hw77 n hw97
    Maxi pro in the 77 and short stroke 8mm in the 97...
    They have transformed them.

    And as you said to me once i have stage 7 tuned them now... all bits of dog hair and grass seeds picked out of the gun slips

    I'm currently working on the new "Stage 9" tune. I write your name on the gun bag with a felt tipped pen
