I would suggest checking with Springfield as to whether those parts are stainless. Basically there are two ways to make stainless black, a black oxide process (basically like bluing) and a coating/paint type of finish. Either can be removed by sand blasting, and there should be no reason you cannot polish the parts to a bright reflective finish if that is what you are looking for.
Hope this helps.
