Default AR15 bolt carrier vs M16 bolt carrier

Is this the correct compatibility statement for the bolt carriers? Being a Calif civilian I don't know much about select fire components.

An M16 BCG will work in either an M16 select fire or a semi-auto AR15 But the AR15 BCG will only work in an AR15.

I bought a new BCG that said or work in either. It will dry cycle fine in my AR15 lower but I haven't hot fired it yet. I bought it because it does not have the serrations on the right side for a forward assist to push against. I have a couple of slick side uppers that don't have a forward assist so the serrations on a BCG are superfluous.

Talking

M16 bcg will work in both ar15 and m16.

Ar15 bcg will work in both m16 and ar15.
But the Ar15 bcg in a m16 will not fire full auto
It will only fire semi auto single shots
Since there is not enough material to trip the m16 auto sear

An AR semi BCG will work for semi auto in an M4 or M16 too, it just won’t run the auto sear.

Hold your horses

If you have a Colt, many came with a block that blocks the M16 carrier.

Some of the 1980s-2000 guns made had a block to prevent the longer tail on the m16 from being used
