I wouldn't say they are non-existant. When i bought my carbine it has a "fixed" stock, which of course split. When i was looking for a replacement, I found one original win 100 rifle stock, which was expensive but factory. I also found that Boyd's (RIFLE)has one and that Macon Gun Stocks out of Missouri has a Rifle and carbine stock. Both of the latter 2 options require some wood working abilities. I chose to go with the one from Macon gun stocks, and sent it to a cgn'er who finished it, as it looks in the picture above. If you decide to go with the Winchester 100, PM Smoji on this board. He is the gunsmith i use for my 3 100's, and has excellent woodworking skills.
