Olympic Arms Manufacturer’s Notes:1. There were some odd variations and some custom serial numbers mixed in thru the years also. And, some receivers manufactured after the ban have the year stamp after the model name, not in the serial #. And if you don"t see a year stamp on the receiver, it is not necessarily pre-ban. 2. Serial numbers that end in "D" were duplicates and one was changed using this letter. 3. Recently some serial numbers have left with one or two letters followed by FIVE numbers. The last numbers are either 5"s or 0"s. 99.9% of these are post-ban. 4. "Older" does not always mean pre-ban as per Corey Sattler. 5. "BL" serial number series lowers are transitional with some pre and some post ban. If you have a "BL" you’ll have to call to verify for certain.
