    Supplies of replacement A1 birdcages lasted until the 2000s, when they were finally classed surplus to requirements.
    Those were some really old M16A1s. The 3-prong FH was dropped from the M16A1 in Dec. 1967. Even the later XM16E1 and Model 604 were eventually outfitted with A1 FHs before ceasing production, but most were produced with 3-prong FHs. The good thing about the 3-prong and A1 birdcage FHs is that they did not need to be timed. The A2 FH does because of the closed portion needing to be on the bottom.

    I swear we had some, not many, M16s with 3 prong FHs in Army Basic (1986). We certainly had a couple guys with chrome BCGs. I envied them because they were easier to clean.

    I'm sure you did. 3-prongers remained in service for years after that reported drop date. On my second go around in the military, I saw them in the late 70s in Korea and early 80s down at Benning.

    Flash hiders were replace for cause, not just to make all the M16s "up-to-date".

    The dates given were the production cut overs. By 1967, how many M16 and M16A1s were produced? I think somewhere in the half to 3/4 million range. And no M16A1 got an A2 flash hider until they started to be re-manufactured as A2s

    What determined the size and shape of the cut-outs on the A2?
    Big brother is watching...and listening.

    The A2 was a no-brainer. It had to fit the size envelope (and blank firing adapter) of the A1 and offer similar flash supression. Port shape followed the A1, probably as much for aesthetics as any other reason.

    Tooling on hand.

    The cut-outs for the A2 Compensator are the same as those on the A1, they just did not cut the bottom one and moved the rest of them to the top half.

    The external dimensions were dictated by the, then NATO standard, rifle grenade.
