Introduction: K'nex RBG Hybrid Gun

About: K'nex guns, TF2, and Valve games are what I like to build/play.
A combination of this modified and the extension idea from this.
The first gun has a kick-butt trigger system that I changed a little bit, and the second had the extension that you could add on, which I thought was pretty neat. It's fun to use, like a pistol but for longer rubber bands-or for more power using smaller rubber bands (assuming they don't break).

 Anyway, a cookie to both of them. :)
Cookie 1--> O
and cookie 2 --> O.

Criticisms are welcome.
