About: Hey everyone, welcome to my Instuctable, or my Instructables page. Well I hope you like what you see and if you do, don't forget to SUBSCRIBE. I like to build just about anything from airsoft guns to fishing...

This is the biggest and most powerful thing Ive ever made. Its over 5ft long and insanely powerful. It tore apart poserboard without ease but it depends on the rubber bands. Please rate and subscribe.

    Love the octopod but the whole thing doesnt look very attractive and also, the "big round" looks quite flimsy
    but overall, good gun

    Considering that is shot over 200ft with really good rubber bands i was thinking about postin but i took it apart a while ago so i wont post

    Actually its very strong compared to its looks but the sides and bottom are in fact reinforced now but the top cant be because it needs to be open in order to load the weapon :)
