I know it has been a couple of days, but I have been mulling this over. If I was Cerberus/Freedom here is what I would do.
I would keep the ammo division intact. It is an obvious money maker, even if shortages slow down there are TONS of firearms out there with the sales numbers we have been seeing. Keeping a consumable commodity makes sense.
Then they should split off their firearms division and sell it. The name still has some value and they also have new state of the art plants in Kentucky and Alabama. It could provide an inroad for a foreign manufacturer like Canik, KBP, IWI or CZ. Honestly, CZ would be the perfect fit.
Buying Remington would give CZ domestic manufacturing for their products. They could also use the Remington name for entry level fare. Keep the RM380, add the RAMI, the 870 shotgun, etc. CZ could be upper end handguns, sporting rifles, shotguns and sub-machine guns... all of which they have in their current catalog. They could then more easily market their products to government and LE.
Close Ilion, NY down, cut the fat, and define both lines. It makes me wish I was running CZ so I could pitch it to Cerberus.
