Hi! First off, to make sure I don't get yelled at, the knex gun is actually the Jackal v4 by DJRadio on Instructables. He's very good at making knex guns, you ...
This short video shows you how to make a basic k'nex gun with not many parts, it works well , sorry for the poor sound i will speek louder next time :-)
I have uploaded the videos for my instructables to youtube. For more information, photos and instructions, see: http://www.instructables.com/id/Joe/ Thanks!
