not sure how custom you want, but I just purchased a mosin sporter style stock for my brother for christmas, bought it through cheaperthandirt.com and paid about 70 bucks including shipping, just waiting on his wife to secretly deliver the rifle to me so I can fit the gun to the stock and wrap it up for his christmas present. it still has the original wood stock but he tried to modify and sporterize it himself...he failed...miserably. I am also going to correct his attempt at mounting a scope and finally get the rifle sighted in for him. my brother is good at many things, gunsmithing is not on that list, I usually do some for all my kinfolk
