This is an old thread, but I just picked one of these up from my local Gun Store at lunch today.
I haven't had a chance to tear it down completly to see what it is made from yet, but I will do that later tonight when I get home.
What I can see.. New receiver with a 70XXXXX serial number,WWII SA bolt with an A9 heat lot#, WWII milled trigger guard, wide base gas cylinder, single slot cylinder screw and a new manufactured .308 marked barrel. The wood appears to be a Boyds target/fatty walnut with a beautiful grain pattern. All of it parkerized to a dark gray/black.
I'll be putting the OEM stock in storage and dressing it in a USGI birch for daily use.
