Exciting update! (Exciting to me, at least.) CMP shipping label arrived last Monday to send in my carbine. An armorer called this morning to say they were ready to do the re-barrel and ask if I had any questions. They just called back to ask if I needed a sight blade, but they've already got the barrel on and headspaced. I'd guess there's at least a chance the old girl will be in my hands by the end of the week, or at least by next week. Can't wait!
