It should be only one letter. A was 1980 and B was 1981. There were only double letters used from 1943 to 1953… and each letter was the same. Ex: MM, PP, ZZI just put some money down on a 700 left handed model BDL in 308. I was just trying to find the date of manufacture.
I think it's also a 1981 model. Ser.#B68513xx. The barrel code in stamped a little lightly, marked AB or AR.
I'm pretty sure it's a AB since the Ser# is in the B range. I was thrilled to see a 308 in lefty!
I'll pick it up at the end of the month.
