Has any one seen a keyhole (Cerro) + CAGE code Colt upper?

I have a few of the square marked (BAFE) but have come across one with what might be a laser etched cage code and a keyhole (Cerro) forge marking.

No gray dry film lube inside and the CAGE code looks laser etched to me, not roll mark or dot matrix.

Yes, a handful. Roll marked CAGE though.



Edit:

You stated that yours is roll marked and then say it appears to be laser etched?

My apologies. Yes, it looks laser etched but could be mistaken. Pic added and correction added in OP.

Gotcha.

Assuming that is roll marked but I may be way off base. Sometimes difficult to tell from a pic vs having it in hand.

Yea it’s really hard to tell. The font looks right but the numbers look extremely uniform and not like roll marks I’ve seen on other examples I’ve owned.

The Colt CAGE code uppers I’ve had typically have the forge mark under the last picatinny slot as well.

Yeah that upper doesn't look right, looks etched to me. Here's 2 Colt rolled marked cage code uppers for comparison.

Because if it's a fake, somebody over paid for it.

That makes sense but how do we know that Colt didn't just change their manufacturing method like they did with the markings on the lower receiver?

I checked my collection and I have one just like your pic. The upper is a laser etched 13629 from Cerro.

It's from a M4A1 SOCOM I purchased in 2/22.

So it seems legit...unless Colt sold me a fake.
