Over the years, Colt collectors have periodically had access to releases of contract overrun LE6920 carbines that were destined for the Mexico National Defense Secretariat. The last release that we saw was in 2017. The release at that time was a Colt LE6920 with standard handguards and detachable carry handle. There was also a variant with Magpul stock, pistol grip and handguards. From what little is known, it is estimated that about 750 carbines had been made available to the United States civilian market. This release of Mexico government carbines was the last release to have rollmarked government markings.
With no hint to the civilian market ahead of time, around March 25th, 2021 Clyde Armory stores in Georgia posted the 2021 LE6920M001 Mexico government overrun carbines for sale on their webstore plus they had the carbines on display in their retail stores. Clyde Armory stated to me that they made a little less than 60 carbines available to the retail market. Clyde Armory was the only retail store to receive these Mexico overrun carbines from Colt. However, it is believed the Clyde Armory made a small number available to a few other retail stores. I have to take a minute and compliment Clyde Armory on doing a great job with the sale of these carbines. They limited the quantity that each purchaser could get so that someone wasn’t able to hoard what was available and jack the prices up to other collectors. The purchase process was smooth and efficient and they shipped fast. I had this example at my FFL in four or five days.
One of the features that sets the 2021 Mexico government overruns apart from standard LE6920’s are the Mexico government markings that are laser engraved and appear in silver highlight. The previous Mexico carbine versions, as shown above, were rollmarked and colored in the same color as the weapon anodizing. The text of the markings is S.D.N. MEXICO CD. MX.
Not able to speak Spanish, I reached out to a friend in Mexico for some help with translating the Mexico government markings. The various sections of the markings translate as follows:
S.D.N. = Secretaría de la Defensa Nacional ( National Defense Secretariat)
MEXICO CD= (Ciudad de México ) – México City
The LE6920M001 ships in the traditional Colt cardboard box. This carbine featured a new barrier bag design that I had not seen before as well as a new accessory set bag. What was really odd about the carbine barrier bag is that it was sealed at both ends and the carbine could not be removed without opening the barrier bag.
For those of you that are not familiar with firearms destined for Mexico, they are required to be provided with an expended shell casing. Colt has this expended shell case in a small bag that is inside the barrier bag with the carbine.
It is said that each firearm that uses an extractor leaves a unique imprint on an expended shell casing…that no two firearms will ever have the same extractor imprint on a casing. This concept is much like human fingerprinting. The Mexico government takes these expended shell casings and records the imprinting into a national database. They can then run imprints on shell casings found at crime scenes through the national database and determine additional information about the the firearms used.
Other than the Mexico government markings, expended shell case and new plastic bags, these carbines are a standard LE6920 that would be found on the U.S. retail market. They are semi-automatic only, 16.1 inch barrels, 4-position receiver extensions with carbine stocks, standard handguards, Magpul MBUS sight set, etc.
In addition to the carbine, there is an accessory package included in the shipping box.
The accessory package includes a military specification cleaning rod set with three rod sections, handle section, bore brush and chamber brush. There is a military specification (NSN marked) nylon sling, Spanish operators manual and two Magpul GEN M2 30-round magazines.
Now we will take a look at the carbine details from stock to flash hider. The stock is a standard carbine stock.
The upper and lower receiver is typical of the Colt LE6920 series. The receivers are made of 7075-T6 aluminum and anodized. The upper receiver has Colt’s CAGE code ‘13629’ and the ‘square’ Brass Aluminum Forging Enterprises forging mark. The lower receiver has the older ‘M4 Carbine’ rollmark along with the ‘safe’ and ‘fire’ selector position indicators, the Mexico government markings, UID and serial number.
The carbine uses an H buffer.
The rear sight that equips the carbine is the regular Magpul MBUS folding rear sight.
The pistol grip is a standard A2 grip. It is marked ‘F1’ on the inside next to the grip screw.
The handguards are standard Colt double heat shield, 7-hole composite handguards. They are held in place by the handguard cap and upper receiver delta ring/barrel nut.
The front sight is a standard forged front sight base with a standard square front sight post. The forge code appears to be <B>2
The barrel has the following markings on the top of the barrel: CAGE code 13629 MP 5.56 NATO 1/7
The barrel has a standard A2 flash hider.
The barrel extension has the ‘o’ and ‘4’ manufacturer marks on it. This combination of marks indicates a Colt barrel extension.
There were not any visible manufacturer markings on the outside of the barrel under the handguards. Typically, you would see a barrel date or a chrome-lined indicator but both marking types were not present on this example.
The carbine has a standard charging handle and automatic bolt carrier group.
There were no manufacturer markings on the bolt or the extractor as normally seen.
Overall I am very happy with the addition of this unique carbine to my collection. I was excited to get the opportunity to purchase one of these 2021 LE6920M001 Mexico government contract overrun carbines. They are always priced reasonable when they first enter the market, are a good conversation piece and an interesting addition to the collection. Throughout the various carbine sub-assemblies there was very good fit of parts and a consistent, high quality finish. Some would balk at the absence of exterior barrel markings or the absence of markings on the bolt/extractor but I don’t get spun up about it. I understand that sometimes those markings are not required by contract and just are not going to be there.
I do not have any plans to shoot this carbine. This will stay in like new condition with the majority of the rest of my collection. If you get a chance to pick up one of these rifles from a current owner, I recommend it as the value on these typically increases pretty quickly. Thank you to Colt and Clyde Armory for making these carbines available.
