The Krime Wave's accuracy is actually only five. That, along with the stock and gas vent, are probably why the Ingram is more than twice the cost. I'm sure, as well, once Run & Gun is released, having those three mods built-in (and thus not taking up mod capacity, if it's like SR4) will be a considerable benefit. But I am also with Namikaze, in that it's probably to make that gun more prevalent in certain areas.
