That's what I'm saying. It's clearly a heavily modified slug-firing HMG modified for high-burst close-quarters gunfights, based on his time fighting in spaceship corridors (or whatever you want to justify it). Qiang Gao's gun is modified enough from the standard model that we can do whatever we want and whatever is necessary with it. Nope. No way. Not while he can still join fireteams. Keep that B6 crap out of Infinity.
