Introduction: K'nex Minigun, Should I Post?

hi,
this is my new minigun, If at least twenty people ask me to post it within 1 week I'll post it.
here are some details:
What I want about a minigun/machinegun is not a high firing rate, I think it's not usefull at all in combat because you've got to reload all the time. so that's why I made this one have a firing rate of: 250 RPM.
Range: 20 feet.
reloading time of one round: 4 seconds.

Further it has a new and innovative (true) trigger system and the fake barrels are actually rotating.
here are the pictures:
