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 208 16" Stainless varmint 209 Moly 7" Pistol; 210 Moly Mid 212 Chrome-lined Mid 213 Moly light-weight Mid-currently discontinued 213CL Chrome-lined light-weight Mid 215 Stainless Mid 218 18" Stainless varmint 219 Chrome-lined light-weight R4, 1:9 220 Moly Std (rifle) 221 Chrome-lined Std (rifle) 222 Stainless NM(rifle) 223 Stainless NM (rifle), unthreaded 225 Moly 10.5" 225CL Chrome-lined 10.5" 226 20" Stainless varmint 228 24" Stainless varmint (1:8) 229 24" Stainless varmint (1:12) 232 Moly light-weight CAR 232CL Chrome-lined 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. Steve/RRA Edited 07-07-06 to include chrome-lined 20" rifle bbl (AR0221). Edited 01-04-07 to include chrome-lined lightweight R4 bbls (AR0205 and AR0219). Edited 01-30-08 to include the 7 inch (209), 10.5" (225) and light-weight CARs and Mids (232 and 213) Edited 09-26-11 to include some information and fix a couple of entries |

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

| 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 |

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 |

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

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!

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? |

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. |

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 |
