FA Final Production

I may have asked this before but I can’t recall if I got any good answers and I am a dunce when it comes to using the search function.

Anyway, what cartridge and headstamp was the last to be made at Frankford Arsenal in quantity.? Not experimentals or souvenirs or stuff like that but an honest to goodness regular production.



“Final Production” can be sort of a two headed coin when it comes to an exact date. In 5.56/.223 the last date I have is FA 74, but some FA 73 &
FA 74 cases were loaded as late as 1976, being used in tests

Why did Frankford close in the first place? I came here in 1978, well after FA closed. Was that the central location in a large city or something political?
