How can you tell if a Colt upper is REALLY a Colt upper? I don't see any markings on it.

usually by the markings on the upper or bbl.

Barrel is an EMCO. I found what the "LK" marking on the rear of the carry handle (on the A2) is... says it's a FN / Kaiser.

The other 2 uppers (flatops) both have "C AF" which says they are Colt / Alcoa Forge.

I am NOT familiar with the FN / Kaiser. Can someone throw me a clue or two please??

Thanks,
David

"LK" is LAR / Kaiser.

Ok so we know that "LK" = FN / Kaiser or
= LAR / Kaiser

Does anyone have experience with these uppers?? What quality and so on?

Thanks,
David

If it were FN, it would be "FK".

I was just going by this

LK FN / Kaiser
LM LAR / Martin Marietta (Army Spares Contract)

that's why I was wondering. It says a LAR is a "LM"
