Metal storm is a good idea.No moving parts inside the gun except the bullets.But how to reload it in a war zone needs more research.Also the portable version for soldiers if any is a design challenge as bullets are simply kept in straight tubes.But i am very very excited about this wonder baby that one day it makes our life really really safe.Simply install these guns, along with cctv, i mean smaller version(my idea, yeah)and lets see whether any one gonna mess up around...
