kb,
It was the fit that just didn't seem right to me and it wasn't comfortable at all, especially when I fired that rifle from the bench. I "felt" the recoil a lot more than I did when I had a McMillan stock on that same rifle. Of course, you could shoulder the same stock and love it. Everybody is different when it comes to shooting rifles.
On the quality issue, I'd probably say it was on the same lines as the factory synthetic stocks that come with new Winchester rifles. In my opinion they ain't that great, but like I said, you might like it.
With the many different configurations of McMillan stocks that are available for the Winchester Model 70 rifles, I think you'd do a lot better getting one of those. However, McMillan just ain't the only stockmaker out there that makes good stocks either!
