    It is a fantastic gun but in order to get it to shoot you must use loom bands as ammo and you must get rid of the grey 2 way connector and the green rod aswell on the trigger mechanism.also when loading hook the rubber band on the in-between parts of the snowflake connector (don't hook it in the part where you would usually attach a knex rod). If you do these things then I will guarantee it will shoot.

    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.

    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 )
