The third member of my Sternguard Squad (slightly more legal then the others) carrying a silenced, Stalker Bolter with a fore-grip.
The silencer came off a spare sniper rifle I had left from some scouts. The helmet is from a Greyknight Terminator with the vents filled.
I've run out of heavy weapons for the moment so I'll probably do a five man team carrying bolters next unless I have an amazing idea. I am trying to come up with some mildly interesting customised bolters so hopefully that'll keep these guys looking varied.
