The AWB started in Sep. 13, 1994 up to Sep. 12, 2004 so we shall call Colt AR that were made during that time are post ban, all that are made before the start of the ban up to 1964 are pre ban, I posted a link below of serial number reference of most Colt models pre ban and post ban (but not all - the list is not complete).

When the ban sunsetted on Sep. 13, 2004 we could just call those AR no ban.

There are some pre ban Colt models AR that are not desirable in my own opinion like the ones with protruding sear blocks on the lower receivers, they started doing that around 1990 up to about 1994, also most of those have the half moon bolt carrier where the lower rear of the carriers was all machined off.

Also less desirable are the large size 0.170" diameter hammer and trigger pins which started about 1989-1990 up to the mid 2009, before those since the start of the SP1 in 1964 and after mid 2009 the hammer and trigger pins are the small mil-spec size of 0.154", to me the small fire control group pins are more desirable because some aftermarket match triggers cost less than with the large pin sizes, also all other non Colt brands uses the standard small pins.

Most Match Target series AR are post ban that started on 1994 after the ban law was adopted, early ones had the lower receiver sear blocks but early in the ban era they changed it with an un-machined web above and in front of the selector of the lower receiver, until current production there is still the un-machined web which is mandated by the BATFE regulations.

After the ban expired in 2004 all the restricted law enforcement models with law enforcement restriction markings on the right side lower receivers mag well, flash suppressors, bayonet lugs, carbine collapsible buttstocks, and high capacity magazines and drum magazines were all legal to buy and own.

Any particular Colt model you're interested in, standard government profile barrel rifles, HBAR rifles, lightweight carbines, M4 carbines, or HBAR carbines?

Here's a link of Colt pre ban and post ban serial numbers.

Thank you for the great information.

The info that I stated about pivot pin, hammer and trigger pins, and markings are in general usually the way it is but there are always exceptions with Colt.

Between 1989 and 1994 when the factory was changing the sizes of the pivot pins and hammer-trigger pins they also released some rare small number of odd combinations.

Like rare lower receivers that have small size pivot pins with small size hammer & trigger pins, there are some that have large pivot pins with large hammer & trigger pins.

Starting the beginning of the assault weapons ban in 1994 up to about 2011 some rare Law Enforcement lowers does not have the LE restricted markings on the right side.

During the end of last year they released a batch of LE6920 carbines roll marked "Colt's Law Enforcement Carbine" with LE restricted markings on the right side of the lower receivers, the last of these LE restricted marked carbines officially ended in around 2012 which the last 100 units included certificates from the factory that they were the last 100 units with LE markings.

Also with the same model some are marked "Colt Mfg. Co." some are marked "Colt Defense" at the left side rear area of the lower receivers, they have no consistency.

I am a younger collector and through the years I have a small collection of 6. Looking to add more I am really wanting to add a 6920/6940/6721 with the LE roll mark to it since I have a LE 6450. Along with a M/T 6601 with the pinned on flash suppressor Blue label box, Sp1 large pin 8xxx serial # range made in 1978, a fall real tree hydro dipped 6721 which was cataloged in 2012 but I couldn't find until 2013. Which is no longer in the catalog line up and maybe no longer produced but please don't hold me up to it. A le 6921 with no roll mark funny you said rare I didn't think it was is there anything I should look for on it? It was purchased new by me complete in the box with the blue label. Along with a LE 901s early production and finally a early Colt Competition (pro) with a sure fire muzzle brake. And while I'm at it a LMG upper. In the link that I have provided I feel to some degree that it is slightly off as my LMG ro750 sporter does not have a forward assist. One thing that I have learned is that you can't simply chase them all. As Colt changes things so much. I am also looking for a lower for my LMG upper what would you recomend ? I have seen the prices for preban lowers to be rather high. More than likely this would be a shelf queen. I'm just trying to round out my collection to a certain extent .

The link that you shown are mainly for movie military weapons clones, they won't have much info on civilian Colt AR models.

The good reference books to have are The Black Rifle by R. Blake Stevens & Edward C. Ezell and Black Rifle II by Christopher R. Bartocci, the first book are the early defelopement of the M-16 and the second book are more modern models from M-16A2, up to the current M-16A4/ M4 carbine plus some commercial models.

It's nice you have a LMG upper, even if it doesn't have forward assist that's still cool, I wish I also have one just for collection.

For the lower of your LMG upper it depends, if your upper is Colt gray color I would suggest getting any pre ban Colt A2 type lower with the raised fence around the trigger guard and preferably one with a small size mil-spec pivot pin, gray color to match your upper color.

Online check out BiggerHammer.net and the AR-15/ M-16 Retro forum tacked threads.

I'm a brand new forum member and Im seeking info related to a blue label boxed 6920 I purchased as new old stock back in approx 2008. It has the "Restricted/Government LE/Export Use Only" roll marks on the right side. It also has a sear block, large pivot and rear pins and large trigger group pins (which I discovered when I bought a standard Timney Match trigger group). It has an LGC serial prefix which I have been unable to research. I can't seem to find any info on aprox date of manufacture or production numbers. The two mags included are dated 9-03. It is marked as "AR-15 A2 Government Carbine Cal. 223" with Colt Defense Hartford Conn USA above the trigger. The barrel is the lite taper pencil barrel with "O MP 5.56 1/7" roll marks. Any help or links would be great.
