I have a 670 takeoff stock on a M70 Black Shadow 270. Sort of a old, cheap Winchester with an older, cheap Winchester stock kind of thing....Anyway, the wood is fantastic. It is precisely inlet, well-finished with a satiny quality(might be age), and very hard wood. It is not walnut, but a very hard wood none the less. Don't know about the rifle, but the stock is great for what it is worth.
