Nickle/Chrome Stripping Question

[browningautorifle]

How can I get it off?

We removed chrome from a batch of 1911 frames that came in two decades ago with silica glass beads and it took all of it off, chrome and copper all at the same time. It doesn't damage or remove features like sand blasting and you can see the color of the metal changing in the lights of the cabinet as you go. This would work for the remains here. You need to do that anyway to prepare for your blue next...
