Every Leupold scope produced since 1974 will have a letter included in the serial number acting as a date-code. Scopes using a letter as a prefix (the beginning of the serial number) were produced between 1974 and 1992. Scopes using a letter as a suffix (the end of the serial number) have been produced after 1992. On the chart below, you will notice the letters �I,� �O,� and �Q� have been omitted as they are easily mistaken for �1,� �0,� and �0� respectively.
