The Interarms MarkX is a solid example of a commercial M98. Good shooters, though not exceptional, and very reliable. I have 2 rifles built on MarkX actions. This is the same action Remington uses for their new rifle, the 798. Parts are available, though not as common as they once were, due to Remington grabbing the import rights and not importing actions as well as the barreled actions they turn into finished rifles.
Remington did not buy Zastava or buy the rights away from Charles Daly. CD advertised their rifles for 2 years before they actually offered them for sale, then had no real quantity of retail outlets to move any real volume of guns. In any business venture, if you make the goods but don't sell them, you will go broke before long. Zastava just made a business decision to move more rifles. I don't think Remington is living up to their expectations, though, with the heavy laminated stocks they put on the 798 turning the rifle into a club rather than the well-proportioned stocks Interarms used to have on their rifles.
