    i built it at home and it doesnt work

    but figuretively it would work

    keep up thy good work

    When I pull the trigger, the circle connector won't spin. Even if I don't put any of the rubber bands on the trigger, it is still stuck.

    Thanks dom

    Dude this is awesome great ible

    I don't think that anyone would be short a green rod. You can take apart other creations if you don't think they are too good.

    Every time i pulled the trigger, the 2 way would get in the way of the white connector, thus making it now spin :/

    ok try and put more rubberbands on the trigger to make the grey connector to be pulled back to the original position ( before being pulled )

    Why should he? He isnt going to try to make the "perfect war gun". This is just a small rbg.

    He has a point though. RBGs are just as good and more fun for shooting indoors.
