I have an AI AT, and am wanting to get a new barrel made for it.
I am wondering what AT barrel profile I have, the old AT profile, or the 2018 AT profile.
Do the first two numbers of the receiver S/N indicates the year of manufacture, and what is the difference between the older profile, and the 2018 profile?
thanks in advance.........
