PRE BAN AR 15

Browse a large collection of guns and ammo from Bushmaster Firearms. Popular firearm models like the ACR and XM-15 Carbine. Shop Bushmaster AR-15 ammo, as well as magazines, and more. Jan 20, 2014 Spent some time last week with Bushmaster trying to find the original date of manufacture. No luck, records don't go back that far (LOL). Lady I spoke with told me any serial number L051000 or lower was an assembled Pre-Ban Rifle.

PRE BAN AR 15 information is very valuable to shooters in states that maintain an ASSAULT WEAPON BAN. While I dont normally advocate borrowing content from other websites I feel this information is invaluable and needs to be protected, duplicated and shared for the greater good of the shooting community.

If anyone has more information and links please post them at the bottom and I will update the list. If you have a lower of from one of the lesser known brands and have managed to verify the date to the serial number please add your info to the comments and I will add it to the master list.

OLYMPIC ARMS

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 AR 15 was produced. Please read all of the details on this page because there are many questions 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.

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.
