Hey everyone, I have just finished, yet another K'nex project that i have been working on for quite some time now! It is my new Anti-Material Crossbow. This thing is awesome, it shoots a large projectile a very long distance and "packs a punch" so to speak. I tried to use as few pieces as necessary while still keeping the weapon strong and sturdy. Since most of the structure on the gun is on the bottom I hardly need any support on top because the bottom structure of the gun absorbs all most of the pressure from the rubber bands. Therefore i can have a very piece efficient top structure on top while still giving the small amount of support it needs. Although this weapon is somewhat piece efficient for it's type it still requires a lot of pieces and for the most part, blue rods, white rods, and purple 3D connectors in general.

  • Long Range (50-150ft)
  • Powerful
  • Large Ammo
  • Some-what Piece Efficient
  • Easy To Reload
  • True Trigger
  • Strong Structure
  • Crossbow Increases Power And Range

Well thanks for visiting my Instructable, if you have any questions feel free to leave a comment!

    Eh, I prefer IaC's heavy cannons. This one looks a bit flimsy.

    please post some instructions man

    could you please post some instructions??

    Nice slingshot. It uses rubber, therefore it is a slingshot

    Have you heard of IaC's heavy cannons? They are much better designed and posted fully.
