Perhaps a bead blasting process using softer plastic beads instead of glass or sand to preserve the engraving as much as possible. I would want to try this on a billet of steel with a high nickle content before I used it on a A grade Fox 20. But I think your best bet if you want a non-case colored receiver is to have the action and forend iron French Grayed.
