Introduction: Irwinner's Semi-Auto K'nex RBG ''mod''

About: K'nex guns, TF2, and Valve games are what I like to build/play.

I randomly searched ''k'nex gun'' today, and this came up:

I really like this gun, so I decided to modify it. (irwinner, I hope you don't mind. If you don't want this on the site, I'll remove it).

 So, this is a ''double-barrel'' gun, though both wheels fire at the same time.
 So why ''mod''? It's not irwinner's gun with things attached or part changed, it's more of a gun inspired by irwinner's, though some of the concepts on the gun came from his gun.

 *Update*
I've 'fixed' the gun, it now works pretty decently with the right bands.
 Anyway, it has a true trigger, and can fire up to 16 bands at one time. At the time, though, I have 14, which is pretty close to its maximum.
