I don't know what type of finish is on the stock from the factory. But I have good success with an automotive product called "Maguires ScratchX" used on rifle stocks it brings out the hidden beauty of the wood and polished it up nice. Put a small amount on a dry soft rag and rub onto the surface of the stock, it works wonders. It "does not" leave a dull finish, it makes the finish look highly polished but very nice. Try it on an old stock first and see how you like it.
