Chrome removal advice

I have a stainless marine shotgun that has chrome plating on the barrel; I want to remove the chrome plating from the stainless and give it a matte finish with my bead blaster bead blaster [on eBay or Amazon] . What chemical can I use to remove the chrome, nickel, and copper without damaging the stainless or the environment?

Removing the chrome is the easy part. muriatic acid [affil links] (HCl) will do the trick in probably a few minutes. The nickel is the toughie. My recommendation is to find a good plater that can strip it and will have all the necessary chemicals and equipment for waste disposal. I don't think it should cost too much.
