I think the problem is that the people that actually own Remington don't care. They just want to keep bleeding as much money out of the company as they can and then use Remington as a nice big tax break when the place folds for good.
Since 93 they've been owned by two different capital investment groups (CD&R and Cerberus) that were simply money people with no connection with or passion for the product. That independence can be good when it comes to making sound business decisions but I expect there has been a lot of financial hijinks going on that has saddled Remington with too much debt and even the past 15 years of spectacular gun sales isn't enough to service that debt.
Hopefully some splitting up of business units and bankruptcy will get them in a place that they can be around for a long time to come.
