Both.

Stainless steel also.

Be nice if the bbl action was factory d/t for various iron sights as well and a nice line of irons could be made to fit even a finish blued gun. The finish over the blank screws wouldn't add much cost and would seem to me to be a jig/fixture and machine deal with little labor involved.

Honestly, since this thread was originally about CZ's, the CZ line would look like a natural. They make a good solid action that needs a bit of TLC. If they did that, they could leave the final stocking up to those that possess opposable thumbs.
