[ARCHIVED THREAD] - Colt upper markings?

Can anybody point me to web site that would show proof markings that appear on Colt uppers and what they mean?

Thanks,

-John

Thank you. Interesting, my A1 upper has the letter C and K, that combination is not shown on the site. Does it mean Colt Kaiser?

Yep!

FYI- BRII has a more up-to-date listing on the forging codes.

That site needs to be updated.

Cerro makes uppers for Colt also now.

ETA: to add the pics of my 6920 and my 6601 both with Cerro uppers.
