What do you intend to use this rifle for? Is it an all-weather hunting rifle, ordinary hunting rifle, varmint rifle, target rifle or what? If it's all-weather hunting rifle then I'd go the stainless barrel and coated receiver route with a synthetic stock. If it's a target/varmint rifle I'd personally leave the receiver blue and replace the barrel and stock with whatever you wanted. If this is a sentimental rifle that you hunt with I'd leave the receiver and stock alone and either go with the two tone look or just put a quality, carbon steel, barrel on it. If you like the original stock then keep it unless you plan on regularly hunting in wet weather or extremely humid climates. Otherwise, hunting rifles have been getting the job done with walnut stocks for hundreds of years and I suspect that they will continue to do so for a while longer. The last thing I'd do is bead blast the receiver and leave it in the white. Why have a stainless barrel and a rust prone receiver?
