Overview[edit]
The M4 Type Carbine is a copy of the ColtM4 carbine. The semi-automatic version is marketed to the U.S. civilian market in compliance with the National Firearms Act. A select fire variant can be ordered by military or law enforcement organizations with three-round burst or fully automatic capability.[2]
The rifle's caliber is .223 Remington/5.56×45mm NATO, and the barrel is hard chrome lined in both the bore and chamber. Unlike the current Colt M4 Carbine which features a four-position telescopic stock, the Bushmaster has a six-position stock. It is compatible with most standard AR-15 parts and has the ability to accept all AR-15/M16 type STANAG magazines.
The standard M4 Type Carbine features a permanently fixed 'Izzy' flash suppressor attached to a 14.5 in (370 mm) barrel, which brings the barrel to a total length of 16 in (410 mm). Bushmaster also produces the Patrolman's Carbine variant which features the more common removable 'bird cage' flash suppressor, attached to a 16 in (410 mm) barrel, bringing the total barrel length to 17.5 in (440 mm). Both of these comply with current U.S. federal law which states a minimum 16 in (410 mm) barrel for a rifle. There is also a military M4 Type Carbine which comes with a 14.5 in (370 mm) barrel and a removable 'bird cage' flash suppressor.[2]
An M4 Type Post-Ban Carbine was developed for the 1994 United States Federal Assault Weapons Ban requirements. Since the ban expired in 2004, this rifle has essentially been replaced by the M4A2 and M4A3. Some states in the U.S. have kept these laws, so the rifle is still being produced.
Legal issues[edit]
A trademark dispute between Bushmaster and Colt concerned the use of the 'M4' name. The M4 was developed and produced for the United States government by Colt, which had an exclusive contract to produce the M4 family of weapons until 2009.[3] Several other manufacturers, including Bushmaster, offer M4-like firearms, nicknamed 'M4geries.' Colt previously held a U.S. trademark on the term 'M4.'[4] In April 2004, Colt filed a lawsuit against Bushmaster and Heckler & Koch, claiming acts of trademark infringement, trade dress infringement, trademark dilution, false designation of origin, false advertising, patent infringement, unfair competition, and deceptive trade practices. Heckler & Koch later settled out of court. On December 8, 2005, a District court judge in Maine granted a summary judgment in favor of Bushmaster Firearms, dismissing all of Colt's claims except for false advertising. On the latter claim, Colt could not recover monetary damages. The court also ruled that 'M4' was now a generic name, and that Colt's trademark should be revoked.[5]

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.
OLYMPIC ARMS
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. Double asterisk (**) under Bushmaster, a person on the internet e-mailed me that he had a lower that was shipped stripped (thus not a complete rifle) in 1991 from Bushmaster with serial #0327XX – ALWAYS CALL TO VERIFY.
Advanced Armaments
No information – Apparently machined from bar stock aluminum, lowers are marked as M-15.
American Spirit Arms (Formerly “Sun Valley Traders”)
ALL lowers are Post Ban AR 15. Began introduction of lowers and rifles in mid/late 1998. Noted as having good fit & finish. Also, reported to be manufactured by Lewis Machine & Tool (LMT).
Armalite | Eagle Arms
Slightly over S/N 30,000 was the Pre Ban AR 15 cut-off, call to verify.* (Some Eagle lowers below the 30,000 range were determined to be POST BAN AR 15 by BATFE – call to verify) Armalite sells Eagle lowers, but sells factory complete rifles with Armalite lowers.
Bohica
Made stainless steel lowers, rumored to have also made AR-15 pistols. Lower marked M16-SA. This is NOT verifiable info as it came from the Internet. Out of Business.
Bushmaster
Below L051000 – Assembled Pre Ban AR 15 Rifles and some pre-94 lowers.**

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.
