This is 100% awesomeness, however I'm not entirely certain one would be able to hold this with a single arm, might work better if a handle was added towards the front, just my opinion, still pretty bad ass though.
aahh. I can see it now. That makes a lot more sense, I thought it would be very difficult to fire the was I first saw it but now I understand that the arm is still held to the side of the body. Just makes the coolness of the gun design increase.
