I am the orginal NIB purchaser of a Colt AR-15A2 that I can't seem to locate on the model chart and so I can't quite figure out what variation I own.

The gun was purchased in 1985. The lower is stamped AR-15A2 but it has no fence around the magazine button aka A1 variation.

The upper has the A1 sights (flip only) and not the high fluttin' A2 sights currently available. The forward assist is not tear drop but the round button. It has the case deflector.

The barrel is 20" but only heavy from the front sight forward.

The handguards are the current ribbed style.

I realize I'm spending too much time trying to figure this out and so I'm looking for a little love from someone who is smarter than I.

I'm guessing you have a green label 6600.

Are there any markings on the barrel?

Post a picture when you get the chance.

I'm not sure what a green label means but if you're refering to color, it's the same charcoal/steel gray as other ARs.

I can't post a pic (no dig camera) but it looks like any other AR described in my first post. There are no markings on the barrel, at least to the extent that I haven't removed the handguards so I can't say for sure. The barrel is skinny out of the receiver and then steps up to the HBAR diameter from the front sight to the muzzle.

I hope this helps.

R6500?
Link Posted: 12/28/2005 10:45:05 AM EDT
Frens,

That's what I first thought however, Andy's chart says the 6500 doesn't have a case deflector; mine does.

I know about the case deflector, but the 6600 has the heavy barrel profile and should be marked AR15A2 HBAR SPORTER

20" chrome lined

1/7 barrel (look at barrel markings)

A1 upper (sights)

Handguards (curent style round/ribbed)

ETA: Source: BRII pg. 279

The markings should be between the front sight base and the flash suppressor on a 20" Colt barrel. Are you positive that the entire rifle left the factory with the upper that you have now?

^ +1

look for the production codes on the upper..near the rear sight you should find a "C"...like this:

Green means its a factory reject and you must promptly send it to me for proper disposal into my collection..er a..the trash..

I greatly appreciate all the help. Here's my homework for tonight:

Look at the markings on the R side of the rear sight. I don't know what they mean but I'll write them down.

Look for any marks between the muzzle and front sight.

I'll also get the serial no.

Madness,

Yes, I accompanied my FFL to the distributor for the purchase. The traditional cardboard box was sealed and the dealer and I opened it together to do the paperwork. I've known the dealer for years (good friend) so there is no monkey business involved.

BTW, is there a model no. stamped somewhere or is knowing the combination of the above tell one what it is?
Link Posted: 12/28/2005 4:15:50 PM EDT
no, there isn't a model number stamped on the rifle

btw, check this site: biggerhammer.net/ar15/, it has a lot of good info about marks and their meaning, AR15 variants, etc.

It sounds like you have a transition model made up of obsolete old stock parts. Colt did this to some AR 15s in 1985 possibly in some 1986. It sound very much like a Sporter II R6500 in a transition version of the pre government model R6550. Is your barrel marked 1/ 7 upfront? It should be. No mag fence is normal on Colt Ar 15s till around 1989 give or take a year. You described a Government model barrel profile to a tee except with A1 sights instead of the normal A2 sights. Hence the transition model. The official Colt AR 15 Government model was not released till around 1987. I own a Sporter II 16" carbine I bought new in 1985 and it has a barrel marked 1/7, round forward assist, case deflector, no mag fence, and A1 sights also. Everything A2 except the A1 sights. I remember looking at a model just like yours when when I bought my CAR15 in 1985 at a dealer. Hope this helps ya.

Do I bask in the possibility of owning a true gem or be satisfied with my two headed snake that will likely be the freak photo on Drudge?

I'll get the numbers and markings tonight and come back to the collective braintrust in the morning. In the meantime, remember that mine is a fragile ego.

OK here's the info:

It's marked Sporter II Colt AR15A2

The upper has the marks C and H as in Harvey. From the site that Frens mentioned, this is a Colt first forging. I don't know what the significance is, if any.

The barrel is stamped C MP 5.56 NATO 1/7 which I understand is the A2 marking.

The serial no. is SP33XXXX.

I hope this helps in figuring out the model no. and I'm also curious how many Colt made with this unique combo of parts.

Just call Colt

Per Colt, they only do phone inquires on SA revolvers; all others require payment.

For the AR it's $100.

R6500

I looked at the bighammer chart and initially thought 6500 but then I noticed that that model doesn't have the deflector but I do. Perhaps it's a bastard version of the 6500 but all the other features seem to apply.
Link Posted: 12/29/2005 11:13:38 AM EDT
I had nearly the same rifle, although I later cannibalized it - it was not NIB.

SP1 style "slabside" lower. C7 upper (A1 sights/brass hump). Barrel was an A2 20" 1/7 Gov't.. profile.

A2 furniture all the way 'round.

Markings: AR15A2 Government Model. Must have been real early - SN prefix GS and had a serial number in the low 3 digits.
Link Posted: 12/29/2005 11:14:41 AM EDT
Its a R6500 per Fjestad blue book, it came in various configurations with a 20" barrel with A1 sights.
Link Posted: 12/29/2005 11:34:26 AM EDT
Jelly,

Thanks for your work. I appreciate it. Once again, thanks for looking it up.
Link Posted: 12/29/2005 1:05:23 PM EDT
it's the 3rd. variation of the R6500
