Whats the best for a black walnut M1 stock?

I use marine grade linseed oil. It goes into the wood instead of just staying on the surface. Been doing this for 40 years.
 
marine grade linseed oil will darken the wood/grain. you put it on and let it soak in and wipe the rest off. The more coats the darker it will get, but it will take a few to do it.
