The comments about Midway USA purchase of Bell & Carlson stocks are not quite correct. Up until very recently, most of the Weatherby camo pattern B&C stocks sold by Weatherby were exclusives made by B&C only for Weatherby, and were NOT available elsewhere. An example was the Dark Timber, available only through Weatherby or a Weatherby dealer.
While B&C now offers all the Weatherby colors to anyone, it is difficult to find Mark V replacement B&C stocks from anyone other than Weatherby or an authorized dealer. This might be on purpose. The Medalist model which Weathery uses is the most expensive of the B&C offerings, and the less expensive Carbelite is a bigger seller. The Carbelite does not have the classic Weatherby cheekpiece, and although offered for the Mark V, it is rarely carried by distributors for that reason.
Vanguard B&C replacements are offered through Cabelas and Brownells, but you'll have a hard time finding a Mark V model from anyone other than Weatherby. In addition, the one internet distributor with Mark V Medalist stocks, had a limited selection of colors, action type (9lug/6lug) and barrel contour.
In addition, it appears that ALL of the B&C Weatherby stocks have been closed out by Midway USA.
