Make sure the rubber bands are on both sides of the ammo. Once all the rubber bands are hooked push the white and blue rods back into the center. Remove the pin. Pull the trigger to fire (in case you didn't figure that out).

    I know, just when you want to hate something, the hate button is gone. Where's my hate button?
    ; )

    There never was a smiley button on I'bles was there? However I can reply with a stream of unusual symbols.

    I guess I don't really have anything better to do. Well, maybe I should get to work on my I'ble. I procrastinate too much.

    (On my MHG-1 I procrastinated for a couple months)

    Many people call this a "pseudo semi-automatic" however there is/was quite a debate whether guns like this are truely semi-automatic or pseudo semi-automatic. I don't think a unanimous decision has been reach and whether this is a semi-automatic or pseudo semi-automatic depends on who you ask.

    Well actually, zero is odd according to sources like WolframAlpha and Wikipedia, but I understand what you mean. The term Semi-auto in the K'nex community has different definitions depending on who you ask.

    yeah i think its even because there's no other thing thats odd that you cant pair up with
