PREBAN AR15 INFORMATION RESOURCES | PRE BAN AR 15
PRE BAN AR 15
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.

What does my serial number have to do with a PRE BAN AR 15?
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.

I have compiled this list for the purposes of sharing information only. This is not intended to be used in any way except for personal entertainment. It is a compilation of both personal information and information submitted from others from the Internet. ALL SERIAL NUMBERS SHOULD BE VERIFIED FROM THE MANUFACTURER PRIOR TO ANY PURCHASE OR ASSEMBLY. It should be noted that it is a felony to possess a Post-Ban (newly assembled after Sept 13, 1994) assault weapon.
If any information presented here is found to be incorrect or you have additional information to contribute, please contact me via E-Mail (hkusp40@midmaine.com) and I will update and re-issue the list.
Note: All items marked with a single asterisk (*) are taken from http://home1.gte.net/bblakley/ban/index.htm. The year/serial numbers under Colt SP series was forwarded to me by an individual whose return address I no longer have.

4-numbers only – very very old. Probably machined from bar stock.
1-letter and 4# – older receiver, but forgings. (Some are newer, POST ban castings – call to verify.)
2-letters & 4# – most receivers follow this pattern.
2#, 2 letters, 4# – the first two #’s are year of manufacture of the lower.
2 letters, 6# (separated 2 & 4 – e.g. SA 96 0000) – first 2 #’s are year of manufacture.
“ICR” marked lowers are an European customer’s overrun, has an unused additional hole – all ICR lowers are post ban.
Olympic Arms Manufacturer’s Notes:
- 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.
- Serial numbers that end in “D” were duplicates and one was changed using this letter.
- 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.
- “Older” does not always mean pre-ban as per Corey Sattler.
- “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.
Professional Ordinance
All are post ban (including all of the pistols).

Sendra
Post-ban receivers have a circle milled into the side of the magwell. They were originally bead-blasted to a non-glare finish. All others are pre-ban. (This is unverified info…) Also, they used to be NESARD. Rumored to have been owned by Dick Drasen (currently M&A Parts) and produced lowers only out of Barrington, Illinois. No complete guns were sold (again, unverified info).
Colt Carbine R6521
Colt Carbine R6521 – Is a rare Colt of which only a few hundred were made for export purposes. They are not marked Sporter, AR-15 or SP1. These are the only Colt AR15 type weapons allowed to be transferred among Connecticut citizens
FIREARMS INFORMATION
Remington never (*) (**) used serial numbers to identify the date of manufacture of it's firearms, they however stamped a date code (spelled out below) by the first letter meaning the month and the last letter the yearof manufacture.
BARREL DATE CODE - stamped exposed on LH top rear of barrel after 1920
the following will only be stamped where applicable
#2 Part order barrel (not originally assembled to firearm)
#3 Service section received
#4 Return as received
#5 Employee sale
R.E.P. On the RH side of the barrel will be a Magnaflux, Remington proof & a test mark
If a gun is returned to the factory as a fire damaged, or blown up firearm, the factory will stamp it as a prefix to their date code with a #4 on the barrel and return it un-repaired. Then if the gun is ever subsequently returned to a warranty center or the factory by ANYONE, they will refuse to work on it as an unsafe firearm.
REMINGTON MANUFACTURING DATE CODE
stamped on LH top rear of barrel, 2 or 3 digit, (month first, year after) these will normally only be the last letters as seen below,
with the whole list shown here ONLY if it had been returned for repairs
The anchor shown here with the date code is just a symbol, as many different inspector marks will be seen
The above information was taken from Remington's own information sheet, so if your gun may not conform, then I am also at a loss in explaining.
The factory says all barrels are date code stamped, well I have found some that are not, or if they are, are so erratic stamping that trying to decipher them is impossible.
The photos below may help a bit. Both were taken off Remington 760s, with the one on the left, a 30-06 that I bought new October 10, 1954. This has been rebored to a 35 Whelen Improved. The one on the right again a 30-06, but with a shorter barrel that I made into a knock around quad rifle with pivot mounts.
| Here the R represents November, & the ZZ would be 1953. The fourth digit being a 3 is inconsequential being an assembly number. There is no inspector mark on this side. | Here the first (LH) mark is the final inspector mark, the O represents July, the R would be 1968. And the F again being an assembly number. |

(*) Typically from the beginning, they NEVER used serial numbers to DATE their long firearms, but date codes. That does not preclude them from also assigning serial numbers. However for factory purposes, serial numbers were not the primary method of dating a firearm. Long guns made before 1941 (WWII) were serial numbered, even the 22 calibers. After the war with numerous new 22 caliber models being introduced, serial numbers were not assigned to ALL GUNS until the Federal Gun Control Act of 1968.
(**) On 8/9/99, they stopped stamping the barrels with the date code. They however continued to mark the date code on the end flap of the shipping box for shotgun barrels however. They planned on using just the serial numbers to tell when the gun was manufactured. So there was a 2 year gap in rifle date coded barrels and the normal consumer, or gunsmith would have to contact the factory for this information. They then saw the error of their ways apparently because of being inundated by phone calls and resumed stamping the date code on the barrel on 10/1/01.

You will notice the year code repeats itself, but over 20 years difference. in this instance, you will need to know when each model was manufactured. To find general manufacturing dates it may be best to go to the Blue Book of Gun Values, which does give manufacturing dates of most models. So even if it (the code stamping) was used on the same model that could have been production over MANY years, in all likelihood sights or stocks would be different which would indicate the different date.
You will also notice the month code spelling out BLACKPOWDERX, this is a common code in the firearms industry. Also some letters were left out if there was a chance of misidentifying a date. Also they jockeyed year letters to a new starting point in 1980.
Also for the 870 and 1100 series shotguns there was a code to identify caliber/size of the actions.

If you find marks on the underside of the barrel, they will more than likely be fitters or assembly marks, which mean nothing as to dating the firearm.
I have seen one EARLY 740 S/N 54,9XX that has a barrel date coded May of 1969, which apparently had been sent back to the factory and rebarreled with a original 740 barrel instead of a 742 which was in production at that time.
An issue that people need to be aware of, is that many Remington firearms such as the 870 series of shotguns can have their barrels easily changed or replaced. So, if the barrel is not original to the specific firearm in question the barrel date code may be meaningless. Also if there is a custom or aftermarket barrel installed it will not have these factory codes.
Compunding the issue a bit may be the fact that Remington Arms stamps their final inspector stamps and assembly (product) codes in the immediate area of the date codes. So it may be difficult at times to determine exactly what is what. With that in mind, and considering a lot of variables. If a specific Remington firearm has a serial number, Remington Customer Service is always the first source which should be checked for date of manufacture as they would be the definitive source. There are no publically accessible databases for Remington serial numbers.
With the hundreds of different Remington models produced over the past 200 years, it can sometimes be difficult to determine the age of your firearm.
Overview
Since serial numbers were not required until 1968, your firearm may not have a serial number. For models without a serial number, we may be able to determine the age by the 2-3 letters that are stamped on the barrel. If your firearm does have a serial number, if you will call or email to the address below, the serial number and model number we can determine the approximate age of your firearm.
Contact Remington through their Help Center by e-mail at info@remington.com or call their historian at 1-800-243-9700 Mon-Fri 9-5 EST. (this number may not be operationa since Remington moved to the deep south).
