The Rem 798 is, as per said above made by Zastava, in Serbia (
http://www.zastava-arms.co.yu/english/zastava.htm). The laminated stock Remington are using are from Boyds'.
Zastava have a long history of making firearms and worked together with Brno and other European armories in the past.
Their domestic civilian Mauser (they also make sporting Mannlicher and Kalashnikov) production consist of the Model 70 (and a variant, the M85), wich is what is called a "modified M98", the receiver went through some modifications (just like the Brno and Cz) from the original.
Zastava are known for roughly finished stocks (but the walnut wood they use usually is of pretty good quality, though) - (the stocks usually are easy to fix with a 200 grit sanding paper and some patience). This is said to be the reason why Remington decided to import the unstocked barreled actions from Zastava.
The bedding might also profit of a little bit of work.
The metal parts are not as shiny as the older Mausers, but the finishing is usually good. The metal is of modern alloys and have nothing to worry about.
They also make good quality sporting firearms, including shotguns, rimfires, air rifles, revolvers and pistols. They also make sniper rifles and many military weapons.
Their barrels are known for good accuracy.
The previous well known user of these actions was Charles Daly, who imported these actions for years.
It's sad that Remington decided not to import and offer the bare actions.
