I think they only made this one year (1998). The stock is either a high end fiberglass or Kevlar and I believe it is Kevlar. This is in great condition with Redfield base and rings. If you're interested, please PM me your email address and I'll send you photos. $900 shipped to the lower 48.

Here's a link to the Remington site with info on this model.

The 308 is not listed as a standard offering so it might have been a special order or custom shop item but I'm not sure.
