Well, I had the impulse to do another gatling gun type weapon and settled on this: the Beam Mech Gatling Pistol. The object just above and behind the barrels is a laser sight. only because I also plan to make one that is human sized that would fire something like 9mm rounds or some other small caliber round. I'll get more in depth on the human sized one when i get around to posting it but the mech one will be just as leathal as the arm mounted variants only its easier to handle and allows quicker aim. They can be duel wielded quite effectively with little trouble, aside from that they can do most anything but work at long distances, at long range its a low chance of actually landing a leathal shot on a enemy mech. To elimate quess work when shooting i added the laser sight, come on~ what makes using a mini gun more fun than having a laser sight that lets you know you're right on target?
