Can we get a complete list of both the old and new barrel codes?

Thanks.

Applicable "codes" for 223 barrels:

Old Codes:
Three characters side by side over the chamber.
First Character:  N or W...N for NATO chamber or W for Wylde
Second Character:  8 or 9...8 for 1:8 twist and 9 for 1:9 twist.
Third Character:  A, S, or C...A for moly (chrome -moly Alloy), S for Stainless, and C for Chrome-lined alloy.

Current Codes:
The actual base part number from our parts system/catalog, located over the chamber.  These are the most common.  Unless indicated otherwise, all stainless barrels are 1:8 twist and all moly barrels (chrome-lined or not)are 1:9.  All 16" moly barrels have a NATO chamber, while the 20" moly and all stainless barrels have a Wylde chamber.

200          Moly CAR
200CL      Chrome-lined CAR
202          Moly R4
204          Chrome-lined R4
205          Chrome-lined light-weight R4, 1:7
206          Stainless CAR-currently discontinued

229          24" Stainless varmint (1:12)
232          Moly light-weight CAR

YOU MAY SEE SOME MARKINGS AFTER THE NUMBERS...THE S IS FOR STAINLESS AND THE C IS FOR CHROME-LINED...PRIMARILY TO HELP PEOPLE BOTH IN-HOUSE AND OUT TO KNOW AT A GLANCE WITHOUT HAVING TO REFER TO A CATALOG.  Additional letters are inspection marks.  All barels receive a basic inspection. and some receive an additional inspection, or even two or three...and will be marked accordingly if they have been further inspected.

Where exactly is the marking?  

On top of the chamber, under the handguards.

Dammit, wish I knew that before I put on my RAS-II.    

LoL, oh well...

If you have a strong light you may be able to shine it in and see it.  My Mid length number (212) is 1/2" in front of the delta ring and under the gas tube.

Tag for later

thanks, i needed those

how old are the old codes?

The switchover started last summer.

Updated for light weight R4 barrels 01-04-07.
They will be available for order 01-11-07.
Steve/RRA

Will other calibered barrels be sold and listed here? I am thinking of the 458socom and 6.8SPC or 6.5grendel.

No 6.8s or 458s initially.  No plan whatsoever for Grendels.
Steve/RRA

I bought an upper and lower at a gunshow from an proclaimed RRA dealer. The barrel has 5.56 Nato 1-9 on the top of the barrel near the flash supressor.  It has no other markings anywhre on it of any kind.  The only mark on the upper at all is a keyhole shaped mark to the left of the ejection port.  Did I get scammed?  The barrel is chrome lined and looks to be milspec.  The lower is marked with the RRA emblem and serial number.  What gives?  That barrel is an R4 type with heavy tip and grenade/bayonet lug.

Not an RRA barrel, and unless it is a very old upper receiver (we've been laser engraving RRA on unbuilt uppers and the RRA logo on complete upper halves and rifles) for about three years) it isn't one of ours, either.  If you want to e-mail me withthe serial number, I can tell you how the lower left the factory.
Steve/RRA

I may be the reason why you guys are marking you uppers.  About 3 years ago or so just as the AWB expired I ordered an upper from a Local florida dealer, He said it was rock river.  I looked it over and it did not seem to match the color of my known RR lower.  So I called RR and had a few converstions with people at RR  and after letting them know that people were selling fake RR uppers.  The woman I told this to at the time was shocked the some one was doing that.   I was told after my third converstion the you were going to look into marking your uppers so that people would know they were getting RR.

That being said my RR upper has no markings but it is real because it was bought direct.  Tim

The differentiated markings (complete upper half/rifle upper half versus stripped uppers) has helped to weed out some of the home/shop-builders who were trying to pass their builds off as factory rifles.  We saw it in more than one case, which helped prompt the engraving as a means of maintaining our product's reputation and value.
Steve/RRA

Hmm. I'll have to go check now...

On your Entry Tactical uppers, How can one tell the 1:7 chrome lightweight from the 1:9 chrome lightweight?

Looking for the 205 or 219 (see the first post in this thread) would be the easiest way.
If it's a complete rifle, I could also look it up by serial number and be able to see how it left the factory.
Steve/RRA

Thanks Steve.  For some reason, I didn't see them earlier.

I bought this rifle at a gunshow today the barrel code is 200-D. What exactly does that mean?

It doesn't contain any literature explaining different features in the rifle either. The SN# is CM141073

Nick,
That's just an AR0200 (200) with an inspection marking.
That serial number left here as a CAR A4 rifle...16" moly barrel, flat top upper, etc....
Steve/RRA

212 C-C = 16" chrome lined, is it 5.56x45, .223 Rem, or .223 Wylde? Thanks.

ME2112:
Nato chamber.
Steve/RRA

I bought a M4 kit from SHERLUK Mark, and the barrel was marked over the chamber" N9C " does that make it a RRA barrel ,and yes it was chrome lined chamber/bore ?

Thanks,

yls

Very old barrel,but yes, one of our codes.  Please see the barrel listing at the top of the first page.
Steve/RRA

Picked up a barrel from pk firearms wednesday has barrel marking 227C supposed to be Rock River 20" HBAR 1-7 twist chrome lined .Not on your list.Is it one of yours?

Yes.
Limited run we did for a specific customer.  We let the overruns out to a couple of dealers.
Steve/RRA

Hey Steve,

 Based on the information from the RRA web site I'm a little confused. Close up pics of the chamber show a shinny ring which makes me think that the barrel and chamber are lined however I wasn't able to find a 200-R with an S above it in your classification list. Can you help me identify this barrel please? Thanks

200-R is just an AR0200.  The R is an inspector''s code.
The 200s (no CL) are regular chrome moly barrels.
Steve/RRA

Just received two new very nice looking RRA SS Mid uppers.  They were ordered at the same time.  One is marked 215 S-M, the other 215 S-, no M.  All else seem to be the same.  Which one should I give to my friend and which one should I keep.  Thanks for the time, great products!

Same bbl...the one just has an extra inspection stamp.  They're all inspected with one set of criteria, and from batches, some barrels are pulled for additional checks.
Steve/RRA

232 C-M

Lightweight CAR barrel 1/9 chrome lined 16".  Just got my upper I ordered and didn't see this particular stamp on the list.  Called RRA to confirm it was chrome lined.

Any chance Rock River will start marking the barrels on the top in front of the sight like other NATO barrels?

Chance of it.  
Steve/RRA

Any chance of posting barrel weights?

I'm most interested in how much weight savings there is between the 16 Inch Mid-Length and the same 'Lightweight' barrel.
(AR0212ASY CHROME LINED Chrome Moly Barrel Assembly, 16 Inch Mid-Length
AR0213CLASY Lightweight CHROME LINED Chrome Moly Barrel Assembly, 16 Inch Mid-Length)

As an aside: Which barrel does the Elite Comp use and what does it weigh in comparison?

The 16" lightweight barrels weight 6-8 ounces less than their HBAR counterparts.  Gwtting weights for bbls has been on my todo list for quite a while, but hasn't reached the top (or close to it, unfortunately) yet.
Steve/RRA

Just picked up a 14.5" 1:7 R4 lightweight barrel marked "197 C-T"
Is this an overrun?  Who were these made for?
Thanks.

We have all sorts of barrel sthat aren't "normally" available (generally due to limitted quantity runs), and as such aren't listed in the first post.  
AR0197 is a lightweight chrome-lined 1:7 with an R4 profiled front end that is generally not available to the consumer market.
Steve/RRA

The letters C M are the only markings I can see on the chamber under the hand guards of the 16" lightweight upper I received recently from Legal Transfers.

My understanding is I purchased chrome lined, 1/7" twist rate- it's what Pete had in stock and met my needs- but want to be sure the barrel code indicates same and I did not see these letters on the list.

Appreciate any help in understanding.

Could you update the list to show what "M" stands for?

I have a barrel coming to me, and its' marked 213 C-M. I think it's chromelined midlength light wt profile. but it should've been marked 213 C-L. So what does "M" stand for? Medium weight? Thx

The C is for chrome-lined.  Anything after that is an inspector's mark.  All  barrels are inspected for the same criteria.  Some barrels are further inspected for different criteria (beyond the basic checks).  These get an inspector's mark (or even two or more if they are picked for another of the secondary inspections).

Steve,

I bought a RRA Upper last week from PK Firearms. I got it today!! Do manufactures usually but there name on the upper. I don't see a RRA Stamp on the flat top? I'm new so sorry if this is a dumb question. How would anyone know who manufactured it if it's not labeled or marked?
Thanks


Toby

No, uppers are not usually marked with the manufacturer's name.
That said, ours are normally laser etched on the top of the upper...either our logo (including name) on the flat over the charging handle (for complete upper halves and rifles) or just an "RRA" on the forward most flat on the rail for stripped uppers.  
Steve/RRA

what about 213W, or maybe M, but i think it was a W.

Mine just has 200 no other marking. Why is there no inspector mark??? Also the RRA logo is on the removeable carry handle should there be one on the reciver it self? THANKS A BUNCH

nevermind, I missed the answer above.

I have 219 c/p  What is the P for?
