Some were made with an FN action - others were made with Zastava actions (Same as Mark X) If you take the action out youll see a little Z in a circle stamped on it...
They are very pretty little rifles, I had one but I couldnt never get it to feed as well as I liked so I had to sadly let it go. (My one was a Zastava action.)
Have one in 30-06. Only minor complaint I have with it, is that it kicks like a mule with my favorite 150gr Speer load. Never weighed it, but it is very light and the recoil pad has "gone hard".
Mint condition when I got it, pencil barrel (marked Harrington & Richardson), Zastava action.
