Yes that rifle was made in 2016 on a cast receiver made the same year.
As afar as we know, norinco made forged M14 receivers from about 1988 to 1994. Virtually all .308 M305s were made from the same batch of receivers up through at least the 2014 assembled guns, many of which are still in store shelves now.
Some people put a lot of hocus pocus on what year the rifle was assembled, often citing pre-2007 or pre-2009 or whatever.
In my view, that's all bunk. Same receivers were used all that time, almost all from the early 1990's.
What did change over the years is the configuration of the finished rifles and the quality of things like bolts, stocks, etc.
