    HW75 Multi-pump?

    Has anyone tried converting the mild HW75 from SS to a multi-pump to boost the power?

    Interesting idea, would need to make a new valve with a check valve on the inlet side.. shouldn't be that hard though (so long as there is enough space)... trouble is multi pumping is a PITA; I like SSPs.
    Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.

    I have thought about buying a secondhand Alecto and swapping the inners into a HW75 but probably dimensions wouldn't work .

    If you get the guts of an Alecto and copy the design, then get someone to make it up to fit the tube of the Weihrauch - which would probably cost a fortune but sometimes people do things as a challenge or for the fun of it - you might get what you want.

    i wish,,,just a simple chamber inserted into the cylinder with a check valve fitted would do the job,as long as you could retain it
