Can anyone with experience offer a suggestion on how to get the same color on the barrels and the monobloc? The mono bloc (and rib) are a deep black/blue but the barrels have a purple tinge. I know the chromium content of B/A steel is high and it contains other alloys too. I have no idea of the type of steel used in the monobloc but it obviously isn't the same hardness/corrosion resistance as the barrels, which are from an ASE Gold. I know it can be done by looking at the factory finish on ASEs & SOs. Thanks for any insight.
