While experimenting with different ideas for a new gun, I stumbled up the "K'nex Rapid fire Slide Gun". I was searching for a fun way to fire a gun, but still have alot of power. And what better idea, then to have it fire with the touch of a hands. Not everyone have those RARE Cyberk'nex motors that Perfect Duck, and some others have, so this build requires no motors, and no hard to get part. The gun can be easily modified to look as cool as you want. Also, it offers 16 barrels on the one I made, but you can easily make it as long as u want, maybe even up to 100! The possibilities are endless... Special thanks to sharpshot99 for the inspiring barrel design. I hope you enjoy the gun. :) I know I did.
Here is the first version I made of the K'nex Rapid Fire Slide Gun.
Here is version II, which features the same barrels, except this time, 20, and extra supports for vertical standing. As I said earlier, there are endless modifying possibilies.
