I have a 30AW. I did a trigger smoothing on it and now it shoots sub inch 100 yard groups regularly with Federal Premium ammo. Put next to a 336 the finish on the barrel is more matte on the 30AW, but the receiver and lever are identical. My 30AW has a gold trigger, and the stock, although not walnut, looks just as good. Since mine has been shot some the action is smooth as they get. I have seen aftermarket stocks for 336 from a number of sources in walnut and synthetic, so I am sure you can find one.
In gun stores I have seen 30s sell for as much, and in one case more than similar 336s.
I hope you enjoy yours as much as I do mine.
