Main article: Notoriety According to, an American sociologist who studies, the firearm was designed to comply with the 1994. The Bushmaster XM15-E2S 'M4 type' carbine gained notoriety for its use in the October 2002.A Bushmaster XM-15 was used in the December 2012. Just before the two-year anniversary of the massacre, nine families of the 26 victims of the shooting filed a class action lawsuit in Connecticut against Bushmaster, and others, seeking 'unspecified' damages for the defendants' purported negligent entrustment and illegal marketing of the XM-15 rifle. Plaintiffs argued that both theories of liability fell within exceptions to the 2005, which affords broad civil immunity to gun manufacturers.

Bushmaster Manufacture Date

The case was dismissed in superior court and was appealed to the Connecticut Supreme Court. In March 2019, the Connecticut Supreme Court reinstated the wrongful death lawsuit, holding that the plaintiffs successfully pleaded a cause of action for illegal marketing.

The trial is scheduled for September 2021.An XM-15 was also used in the 2018.An XM15-E2 was captured from fighters in by during the.

So what would you assume is the born on date? When the frame is milled, or the grip molded or when it's put into a shipping box to the states? Or the day it passes QC and gets fired?

What day is the true Birthday?I would say, the day it's packed in the box, and passes QC checks.Even if you call them, it's a process to build the weapon, doesn't happen one at a time 10 or 20 times a day, it happens in batches or runs of parts. Then they are finished machined and matched in a set, serialized and stamped, go thru QC, test fired and boxed. Click to expand.I always assumed that as well.the day the gun is finished and has a serial number.I did not recieve a shell casing.I bought the gun in Nov of 2004 and the manufacture date was Aug of '04.pretty new for a gun that got from Croatia to here. Through the distributer, to the store.somewhat of a process I would imagine.I bought the 1911 in Jan of '05 and the manufacture date was over a year prior. Guess it collected dust for a while.

Which was lucky for me. It was (still is) a current model (9151) and it's far exceeded my expectations in every way. Accuracy, fit and finish, reliability.I couldn't have hoped for more. (I did handle a lot of 1911s before settling on this one. Can't shoot them new, but you can dry fire and inspect the fit and finish).Peace,D.

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.

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:

  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.
