Hmm, speaking of physics, the barrels rotate at 600,000 rpm's, which would make it insanely difficult to handle due to the centrifugal force generated by the barrels. They would work like a gyroscope. The rate of fire isn't important, the velocity with which the bullet leaves the barrel is! And at 960,000 thousand rounds a second, the bullets would have to travel pretty damn fast just to get out of the barrel in time to avoid hitting the previous bullet in the ass:) To put it shortly, this gun could probably prove to be humanity's only real chance of ever leaving the solar system. It would make one hell of an efficient reaction drive:) Please, don't take this the wrong way, Pan, It's a wellmade prop, but I seriously consider lowering the specs on this baby, before somebody fires it and accidentally pushes the Earth out of orbit!!! Keep up the great work:) Regards Ronin
