When was my scope manufactured?
Every Leupold scope produced since 1974 will have a letter included in the serial number acting as a date-code. Scopes manufactured prior to 1974 will typically have a five or six digit serial number without a prefix or suffix. 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.
