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.
The existence of the Colt M5 has been known for some time but there has been very little discussion of the program in public. Information that is available indicates that the M5 has been tested and/or fielded in three calibers and eight different models.
This post is only going to look at the four 5.56mm models. I am going to show you data sheets for three of the four versions and just an image of the fourth variant. The Colt M5 Carbine models are as follows:
Colt CM556-10H-M5A-SCW 10.3″ barrel 5.56 x 45
Yes, you guessed it…this is the newest version of the Colt Sub-Compact Weapon (SCW)
Colt CM556-10H-M5A 10.3″ barrel 5.56 x 45
Colt CM556-11H-M5A 11.5″ barrel 5.56 x 45
Colt CM556-14H-M5A 14.5″ barrel 5.56 x 45
I have not seen any indication to date that the M5 family of firearms are set for release on the civilian market. My fingers are crossed. I hope you have enjoyed this look at these four 5.56 x 45 variants of the M5 Carbine.
