The SMG would have to have partially bad range because it was because of the scope and, or, silencer that gave it it's accuracy at longer ranges. If you take it off then it will revert back to the SMG that we currently use in Halo 2 and Halo 3. I vote we take the silencer and scope off, but give it a little accuracy boost, but nothing to huge. More than the range it has unscoped and unsilenced but less than the AR.
