looks like decent machine work- so i give an A for craftsmanship- aside from that... it looks lame to me. timing would be near impossible to maintain, seeing as consistency is going to be ballparked at best. 1 barrel or 3, or 6- it'd be a massive ass pain to make sure you weren't chopping. also- like mentioned before- you can only shoot as fast as your hopper feeds. i see one hopper. capacity and speed are both hinder by that. if you could vehicle mount this thing, and run a huge tank, and some type of monster sized feed system it'd be better, but still no more effective than a double trouble at the very best... my final and ultimate judgement= LAME

I would imagine they'd want to work all the kinks out of the mechanics before focusing on a delivery system for the paint. The hopper probably suffices as a temporary solution or simply for testing purposes.

It looks cool, but can't work on the same principle as a mini-gun. Those barrels are spinning at 10g of force. It would rip the paintballs apart.

Wizard, you want to chime in....

Real mini-gun=chamber, rotate, fire, extract, repeat
PB minigun= attempt to align, fire, chop, rotate, loose pressure, leak air, sling shards of shells (but kudos on the looks factor...this one's for the campsite and not the field IMHO)

He uses a warpfeed which is attached to a backpack full of paint.
