Yes, there is a list of all the barrel codes on the RRA industry forum on {elsewhere}.
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.
New 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.

YOU MAY START TO SEE SOME "S" AND "C" MARKINGS AFTER THE NUMBERS...THE "S" FOR STAINLESS AND THE "C" 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.0
