As long as they mask off the back of the barrel and its threads and shoulder to prevent the hard chrome from changing the timing, you should be good to go in that sequence. Alternately, they may just final tweak the shoulder with a toolpost grinder and a diamond point on the lathe.

Industrial hard chrome is very hard. Exactly how hard seems to depend on who you ask. I find numbers ranging from RC 65-72.
