Not yet. I've blued the areas where the salt bath finish got taken off the receiver - but I'm going to try and get at least 350 to 500 rounds thru it before I worry about choosing/applying a final finish.
After the last 2 builds dying an early death due to heat treat issues (all my fault), I'm going to take a more patient approach this time.
I want to get a decent round count going on the ejector, make sure it doesn't peen over or anything, and if it holds up - paint, park, or even cerakote it.
