Hi,

I saw the thread which listed colt AR15 serial numbers, it seems to be the same one which is floating around
in alot of places.

I'm interested in buying a Colt Ar15-A3 Tactical Carbine model# 6721.
The serial number in that list are explained as follows:

BD AR15A3 Tactical Carbine 6721
BD000134 and Below (AR-15A3 Tactical Carbine - very rare model)

The one I'm looking at buying has a serial number in the B001XXX range.
I haven't had much luck contacting colt yet about the serial numbers
So, I figured I'd post here, to see what people thought.

1. Anyone know anything about serial numbers for this model of gun? I think that list is incorrect

2. Where can I find a good value (or you can tell me)? It's brand new complete(not fired), in box, in plastic.

Thanks,
-Rob

Do you know what the differences were, if any (between... pre,during,after ban) ?

Only 134 were made before the ban. These were legal for civilians to own. After the ban started, these rifles were still being manufactured, but only for law enforcement. Now that the ban has sunset, all that were made during the ban are now legal for civilian ownership. They aren't rare any longer.

The first Colt AR15A3 Tactical Carbines will have lower receivers with sear blocks. The lowers on the first 134 guns will not have the LEO markings. These guns also have the pretty gray finish. Later production guns will have the black finish, the LEO markings, and no sear block.

Hope this helps!

From the current Blue Book of Gun Values.

AR-15A3 TACTICAL CARBINE (R6721)

- .223 Rem. cal., M4 flattop with 16 in. heavy barrel, 1:9 twist, pre-ban configuration with flash hider, bayonet lug, and 4-position, A2 sights, collapsible stock, removable carry handle, 134 were sold commercially in the U.S., most collectible AR-15. Mfg. 1994 only.

On the R6721, serial numbers BD000134 and below are pre-ban. Note: the serial number cutoff on this model, as Colt shipped out a lot of unstamped post-ban law enforcement only "LEO" rifles before finally stamping them as a restricted rifle.

Current production version has a different model number - AR6721 and a different serial number prefix - LBD******.

R6721 - Super rare and highly collectable preban.

AR6721 - Nothing special - MSRP around $1300 for an unfired, new-in-box

so then are there R6721 with serial numbers higher than 134, because the one I'm looking at has a serial number BDxxx13xx, not LBD?

*edit*
or maybe another way to say it, when did the R6721 end, and the AR6721 begin... and is there any difference between those two models?

As far as the individual rifle you are considering, only Colt will be able to give you accurate production and shipping dates.

What we do know at this point -

The "for sale" rifle is a unstamped restricted Model R6721, based on the serial number prefix (BD) and serial number (BD001xxx) information you stated. It can't be a Model AR6721. When the AR6721 began production, they had and still have the restricted mark on the mag well in addition to a new serial number prefix of LBD.

Production of the R6721 (both unrestricted & restricted serial numbered) ended in 1994. That does not mean all R6721 left the Colt warehouse in 1994. The Ban ones were serial number BD000135 and above. Colt will be able to tell you when the AR6721 began production but I would guess 1994. I would also imagine the only difference between the last R6721 and the first AR6721 was the lower receiver mag well markings.

Just posted a 6721 data base here:

www.ar15.com/forums/topic.html?b=3&f=118&t=271173

Included is:

BD 001742

May well be the one you are looking at? That rifle would have been made in 1995 prior to June.

Wonder what a NIB "super rare" R6721 preban would bring these days?
