Random Information For Today

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.

I hope everyone has had a good week. Talk to you again in the next day or two.

Colt Lower Receivers Will Now Have Lever Stops

Last night on Gun Broker and M4Carbine.net I saw examples of CR6920’s with intact lever stops.

This is a production change and we will see more lower receivers with lever stops as more production carbines get into circulation.

Now what to do with my CR series carbines that have ground off lever stops? Hmmm.

Current Upper Receiver Markings On 3 New Colt ‘CR” Series Carbines

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.

Hope you find this informational.

Colt M5 Carbine

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

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.

Colt / Knights Armament IAR6940H Upper Receiver Assembly

I got exceptionally lucky recently and had an opportunity to buy one of the Colt / Knights Armament IAR6940H upper receiver prototypes that were part of the Colt IAR program. Below are a few photos. I will write more about this piece soon.

Colt LE6920M001 Mexico Government Carbine

A couple of weeks ago, Clyde Armory in Athens, GA stocked some new Colt LE6920’s that were contract excess for the government of Mexico. These carbines carry the model designation of LE6920M001.

I have started photographing the box, accessories and rifle tonight and will have the photos up here in a few days.

Mexico Government Contract LE6920’s

The end of this past week saw the appearance of another batch of Mexico government contract overrun Colt LE6920’s hit the market.

There is a discussion about them on AR15.com here: https://www.ar15.com/forums/Industry/The-new-Mexican-LE6920-/29-298836/

The last time we saw this happen was in 2017 and the carbines were retailed at $700. This time, the retail price was $1369.95. The market dynamics are completely different this time and this price is still a bargain for a unique Colt collectible.

You can see details of the previous LE6920M on my page here: https://thecoltar15resource.com/le6920m-standard-w-carry-handle/
