Sullivan doesn't know what he's getting into. Once he starts consolidating, other small-arms manufacturers will pop up. Consider Windham Weaponry - they started up when Bushmaster was sold off to the FG, and you have several independent manufacturing contractors sitting around with nothing else to do but had the equipment and know-how on hand....
FWIW, the Tracking Point stuff is pretty cool, but it also means you're chained to a battery all the time. My guess is Sullivan will probably want to buy that next. :D
