The only slight addition is historical, not technical, and that is that the 8620 chromium, molybdenum, nickel alloy actually pre-dates M-14's and was used in M1 Garands back into the 1930's.

Quite right, this is an outstanding thread on fine steel and aluminum, but of course we will never convince the true believers in investment casting, but hey, somebody's gotta buy those guns, and that just means more Smith and Wesson's for the rest of us. LOL
There are several AEs and MEs that post on the Sino Defense forum, they write and present quite well, after doing my own welder and bailing wire engineering/fabrication, I came to the conclusion that the engineers were usually right, the sideline commentaries,,,,, not so much!
