Yay, another machine gun that can kill in 7 hits, considering it shoots at 12.5 per second, it can kill someone in about half a second if all shots hit.
(0.08 seconds per shot * 7 hits = 0.56 seconds)
Funny how people steal the shotgun code for spread too, what's the point of a loop if the contents only happen once?
Aside from that, the model is good, but again with the generic 'real' brown/black/grey color scheme. If I wanted 'real' guns, I'd go play a 'real' shooting game. This is Blockland.
I also say no to bullet holes.
