Sci-Fi Mini gun

I was thinking about creating a stationary minigun which has a sci-fi vibe to it. I used moi 3d to built up my 3d concept mesh. This weapon can be operated manually or fully automatic.

This is successor the destroyer of enemies. When used as auto mode it becomes more a threat like a crocodile in lake with some handicuffed human. Has the elimation of enemies upto 98%. Has a neuclear tiny reactor to produce it's energy.
