If you follow me on any of my social media accounts, you may have already seen this information but I wanted to post it here too.

Over on AR15.com, in the ‘Industry/Colt’ section, there is some discussion about the variance in upper receiver markings of current Colt CR series carbines and rifles. I personally have zero issue with the marking variations but I know some people are losing their minds. I understand why the marking variations happen and I’m ok with it because I believe I’m still getting quality parts. Anyway, here is the information that I posted.

Below is a photo showing three of my recent purchases (within the last 60 days) and their upper receiver markings. Nothing consistent between these three carbines in the new CR family.

Back: CR6920-EPR keyhole forge mark only
No barrel date

Middle: CR6940. stamped ‘C’ and square forge mark. No barrel date

Front: CR6920. CAGE code square forge mark
No barrel date

To demonstrate additional differences, look at the image below that shows the difference between the two upper receiver square forge marks.

Hope you find this informational.
