Q: What
does my serial number mean?
A: Nothing is more frustrating than to
know little or nothing about the firearm you own
or are about to buy. Use the information in
this page to help determine when your Olympic
Arms firearm was produced. Please read all of
the details on this page because there are many
quesitons answered in the following paragraphs.
As many of you already know, on the 7th of
June, 2000, Olympic Arms experienced a
devastating fire that destroyed our sales
offices. In those offices were housed our
current as well as archival records with regards
to manufacture, acquisition and distribution of
firearms. The books that we, as well as all
federally licensed firearms dealers are required
to keep are commonly known as "Bound Books", or
"A&D" (acquisition & distribution) books.
These books, over 25 years of Olympic Arms
history and data, were completely destroyed in
that fire. All A& D book records prior to the
7th of June, 2000 are GONE.
Period. This is an unfortunate situation that
severely limits our ability to provide product
information for any and all AR-15 lower
receivers and/or complete guns manufactured
prior to that date. As a result all that we can
provide is what you see below, a date "range" in
which your serial number was manufactured.
We CANNOT provide you with
the date the serial number was shipped, we
CANNOT provide you with
information determining whether a particular
serial number was a factory assembled firearm,
and most importantly, we CANNOT
determine whether or not your particular serial
number is a legal grandfathered pre-ban firearm.
Many people and organizations have been
critical of Olympic Arms for not securing a copy
of these records elsewhere, or keeping an
electronic file of this data as an emergency
back up. If you'd like to read why this decision
was made, please read the article in the About
Us section titled "Pre-fire Bound Books".
Remember that Olympic Arms fully complied, and
still does, with ATF regulations regarding A&D
books.
Below you will see a list of serial numbers.
At Olympic, we group our serial numbered lowers
into "ranges". If you'll notice, all the serial
number ranges have a letter prefix but one. The
initial receivers made by Olympic Arms simply
contain a 4 digit serial number, no letter
prefix. Each subsequent serial number range
(either beginning with 0001, or 1001) will show
a 1 or 2 letter prefix.
Additionally, you will see several lines for
serial numbers that begin with the same letter(s)
prefix. These prefix series are divided by a
date range to their right. These date ranges are
the beginning and ending dates of the physical
paper ledgers in which those numbers were
recorded. In other words, the ledger books were
not large enough to contain all of the numbers
(0001-9999), in one book. For that reason, there
is a beginning date and end date for each
ledger. That is what you see below.
Match your receiver up with the letter
prefixes on the chart below. Each line is
separated into 5 columns.
Column 1: The serial number
itself (including prefix).
Column 2: The beginning
serial number in that book.
Column 3: The beginning date
for that book. If there is only one date listed
after the serial numbers in column 2 and/or 2,
all of those numbers were manufactured on that
same day.
Column 4: End date for that
book.
Column 5: Comments regarding
that range of serial numbers. The comments as
listed would apply to all of the serial numbers
with the prefix listed to the left.
