EDITED 13 JUL 2021- I have learned that these are not new production but are old stock making it to market. The AR15A4 is still replaced by the CR6700A4.
Colt has a new AR-15A4 on the market. I hope to have detailed photos soon.
The rifle has selector stops and it has a new laser engraved rollmark.
This new AR-15A4 in on the market in addition to the CR6700A4 20″ rifle with the ‘Carbine’ marked lower receiver.

For my followers in the USA, I wanted to wish everyone a happy 4th of July. I have been traveling with my family the last couple of weeks. We finally got back home late last night. Spending some time today with friends.
The image below is from Colt’s Facebook page.
I hope you have a great holiday with friends and families. I will be back to providing content/updates tonight or tomorrow.
Posted this morning on the official CZ Firearms – Ceska Zbrojovka Facebook page.
“Our parent company CZG is today announcing the final stage of acquirement of iconic COLT company. We are really looking forward to the cooperation of our companies and the advantages coming from it. Not just for us, but also for you, our customers.”

I was piecing together the LE6940FDE upper receiver that I have when I ran into a difference with the upper receiver that I had never noticed before.
In the attached photos I have circled in green the part differences that I am referring too.
The retention of the ejection port cover rod on a 6940 upper receiver is completely different than it is on a standard, non-modular, upper receiver (LE6920 or CR6920 for example).
I had never noticed that before. Now I need to identify the roll pin size and order a few so that I can install the ejection port cover on this 6940FDE upper receiver.
About 95% of my Colt collection is firearms or components (upper receiver assemblies, lower receiver assemblies, etc) in their original factory configuration with the original factory parts. However, sometimes I find myself hunting for Colt parts to piece something together.

I try to buy parts from a variety of parts providers. I don’t use only one or two providers because I like to share my support across many businesses and help as many in the firearms industry as I can. However, if prices are not reasonable, I do bypass some businesses.
Some of the businesses that I buy Colt parts from are Brownells, Midway USA, Arms Unlimited, Shark Arms, Apex Gun Parts and Thoroughbred Armament to name a few. Availability of parts often requires me to shop around to find needed parts in stock.
One recent purchase I made was labeled as a Colt upper receiver parts kit from Shark Arms.

The parts arrived in the ziploc bags as shown. The parts appear to be new as was advertised.

If you have opened a brand new Colt firearm (or any firearm really), you know that the oil has a unique feeling and smell. These parts have the same characteristics that I have encountered with a new Colt firearms and don’t show any wear at all so I believe that they are new. The cost of the parts was $55.
The upper receiver parts are going to be installed on a stripped Colt 6940 FDE anodized upper receiver that I got in a Gun Broker auction.
I don’t plan to really do anything with the upper receiver other than to just have it sitting in the collection. But, I thought I would assemble it short of installing a barrel to have it as complete as I can. As seen in the photo below, the parts that were used on the factory completed 6940 FDE upper receivers had the normal dark factory anodizing.
I hope everyone had a good week and have a good weekend ahead. Stay safe.
First I apologize for the lack of posts and content lately. Life has just been kind of crazy. I have been active a little bit on Facebook and AR15.com lately. I’m trying to make it a point to get into coltforum.com more as well. I am minuteman1636 on ar15.com and coltforum.com. I am going to try and participate some on M4carbine.net.
I have made a few purchases over the last few months, some of which I have done quick posts here about. I am going to add some content/pages with more information and data on all of the items. A few example of the content coming up details on the three prototype upper receivers that I have purchased along with content on the LE6960 CCU, CR6920, CR6920-EPR and CR6940.

I will also be starting two separate pages here discussing my efforts to ‘clone’ the Colt SCAR-B prototype and the Colt IAR6940H. I have spoken briefly to D.Wilson Manufacturing who has stated they can help me with the assembly and modifications of some parts. This is a project that I am especially excited to finish. My last big hurdle is getting a Colt LE6940 series gas block/front sight assembly.

If you haven’t been following Arms Unlimited on Gun Broker, they have been selling of some rare Colt gems. Examples are a Paraguay government marked M203 37mm grenade launcher, a Yemen marked CK901 and a CM901 just name a few. You can see their current auctions here: https://www.gunbroker.com/All/search?IncludeSellers=1889752
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 Middle: CR6940 Front: CR6920
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.
