What timeframe did Mueller Brass forge A2 uppers for Colt?

My best detective work leads me to believe it was from 1993 to 1998.
This is only based on a limited number of rifles seen in original owner collections.
Earlier rifle(s) had CM code and later ones from the mid 2000s had symbols, based on the ones I have seen.

Thank you in advance for your replies.

My 2000 made A2 has C AF receiver.
So I guess pre 1998 is accurate

I lucked into getting an upper for my PCR99 and it fits into my earlier question.
It is a Colt AWB upper.

The barrel is dated 5/98.

It did have a setscrew mounted flash hider or brake at one time.

I have an almost identical original upper on my DPMS, except it has a shoulder and threaded FH.
