I saw the Supernova in Ballistic Overkill and thought "haha yes" so I made the rectangular boye available for SMGs.
Also I changed its stats so it's more or less a sidegrade to the medium suppressor (stats when used on pistols stay the same). Dunno if it's good since I don't play vanilla but who cares it looks cool.
Also it's BLT so drop this thing in mods.
