Introduction: Fully Automatic Knex Gun (UPDATED)

FIRST OFF: DO NOT BUILD THIS GUN, ITS A PROTOTYPE!!

This gun is based off of bakenbitz idea and i just improved it and changed it around. Its fully automatic. It works by cranking. I made this gun to shot airsoft bbs but thats just because i like that so u can make it shoot something else if you like. It probably shoots about 3 or 4 per second. It comes with a clip that holds about 23 bbs. If enough people ask for the instructable than ill do it. It still needs some work but it doesn't shoot to far but its a brand new design and there is nothing else like it that i can find. hope you like it. please comment on what you think about it and if you upgrade it please tell me thanks.

    You tell us not to make this gun yet you give us instructions.

    Looks cool! Can't wait to build it!

    I've only got a little gear without tan connector hole, so mine slips cuz it isn't attached to the axle. How do I solve that?

    Get two stub connectors (small blue things with no hole) and try pushing them close up to the gear

    if u use the tan ones with the stubs on them u can connect them in the small holes in the sides of the gears

    But then when the gear rotates, it would be blocked by that tan connector which would cause many problems

    You can't

    I need t say this... i isn't fully automatc, its crank action

    the grey clip is broken a clip to hold the bb's

    Does it work with metal bbs?

    does not work

    it is basicly a gattling gun in rifle size

    As the description says, it's a prototype. I built it too, it is very unreliable.

    when i built one it would blow up in my face every time but i will try again. it is ok if you make fun of me for it blowing up.

    Ow..... That's... Unfortunate.

    I won't make fun out of you. It is a commonly known fact that most full-auto's have a tendency to blow up.
