I will not testify to this in court but I'm remembering Ruger using the letter 'K' to signify a stainless steel item up until ??. This will not be marked on the receiver (IE: KAC-556) but rather on the packaging. My oldest Ruger was shipped in 1949 according to the factory letter and as far as I can tell it never had a real model number. Some new Rugers arrived here this week and they all have a five digit number (SKU) for the different models with no letters. But there were a lot of differences in between. Rugerhas used the numbers only for 20 or so years by my guess.

The old part number breakdown goes like this IIRC: 'AKC-556-F', the first letter 'K' is for stainless, the 'AC-556' is the model, the 'F' is for 'folder'. I have read where there were AC-556 folders with the longer barrels but have never encountered one. The Mini-14 versions are a different story. I've also read where the 'K' was for kurtz, but I doubt that.

The AC's are fun to shoot and reliable. Use good mags and you'll be happy.

The Ruger is Stainless NOT Blued. The form 4 is at the office so I don't have access to it at the moment but I am 99% sure it says KAC-556F and not "K". I will verify tomorrow and respond back if I am wrong. The smg is a factory gun with a genuine Ruger folding stock. I have not fired the weapon but selling if for a widows estate. The gun was purchased years ago and put in a safe, it was not fired by the previous owner either.

You're correct in designation. KAC-556F means stainless short barrel folder. AC-556K means blued short barrel folder, KAC-556 means stainless 18" barrel, AC-556 means blued 18" barrel.
