This table is intended to be used as a reference for the Colt-series of automatic rifles based on the AR-15 pattern. Currently the R6xxx and some of the military 3-digit series are covered, but not all of the information is complete. If you know something about the rifles listed or find an error, please e-mail me and I'll update the table. The colums I'm specifically seeking info on have violet-colored headers.

1 - Colt built several thousand 'bastardized'AR-15's using different lower receivers but the same model number. Dependingon the date of manufacture it may have an A1 or an A2 lower receiver.There doesn't seem to be a definitive list of which rifles have which receiver,or when Colt began using strictly A2 receivers for their AR-15's.

Barrel contour/slip ring/handguard terms

Standard: Original thin barrelstyle. Did not stand up to prolonged firing very well giving reducedaccuracy.
A2: Later style of barrel that was tapered at the front sight to thicken theexposed barrel. Apparently to
strengthen the barrel to avoid bending when G.I.'s used it as a pry bar.
HBAR: Lateststyle of barrel that is the same thickness the enitre length through, ratherthan just the exposed
section. Stands up to heat well and gives better accuracy.
HBAR
stepped: New barrel for the M4 carbine designed specifically with a 'step' to accomodatethe M203 grenade
launcher.
Straight: Slip ringretainer between the handguard and the upper receiver that has a straightcylindrical shape.
Typically found only on early AR-15 and M-16 rifles with A1 upper receivers.
Tapered: Slip ring retainer between the handguard and the upper receiver that hasa slight conical shape. Used on
all new AR-15 and M-16 rifles.
Smooth
triangular: The original handguard usedon early AR-15 and M-16 rifles. Still commonly seen today, not usedon
newer rifles. The handguard is a smoothened triangle shape with vent holesat the top.
Ribbed
cylindrical:Newerhandguard used on all modern AR-15 and M-16 rifles. Cylindrical ratherthan triangular, it has
vertical ribs along the entire length of the handguard for better grip. Vent holes are along the top and
bottom.
Ribbed
shorty:Identicalto the Ribbed cylindrical handguard found on modern AR-15 and M-16 rifles,the shorty
handguard differs only by being shorter to accomodate shorter barrel lengths.
Smooth
cylindrical: Special handguard found only on the7' barrel of the 9mm Model 633. It has no ribs and is smooth
along its entire length.
Square
LMG:Bulky square handguard used on the M16A2 MachineGun to vent heat as efficiently and quickly as
possible. Has several holes in the top and bottom to accomodate specialattachments such as a vertical
foregrip and carrying handle.

Flash hider terms

3-prong: Vietnam-era flash suppressorwith three slits and an open front end. Soon changed to closed endafter
vegetation frequently got caught in the prongs.
Birdcage:Newerstyle of flash suppressor that has six openings with a closed front end. Changed to A2-style to
prevent dust kickup when firing.
A2-style:LatestColt flash suppressor that has five openings (two to either side, two diagonallyupwards, and one up) and
a closedfront end. The lack of holes in thebottom of the suppressor avoids kicking up dust when firing.
Vortex: A highly efficient flash suppressor that eliminates all muzzle flash evenfrom very short barrels. Typically
four-pronged and 1/2' longer than the 3-prong suppressor. Newer modelshave the prongs twisted
slightly counterclockwise.

Sight style terms

A1: Original style rear sight that was adjustable for windage only. Adjustmentsrequired the use of a tool or
bullet tip. Flip-type aperatures for short and long-range shootingare provided, the ranges depending on
the firearm.
A2:Newer style rear sight that is adjustable forwindage and elevation up to 800 meters, and requires no tools
for adjustment.

Receiver terms

A1: The original, non-reinforced, slab-sided lower receiver with the exposed magazine release button. Easily recognizable by the smooth right side. Usually accompanied by a straight pistol grip.
A2: Newerlower receiver with reinforcing around the magazine well and a 'fence'around the magazine release button.
Flattop: New style of receiver that lacks the carry handle. Allows for themounting of a wide variety of optical
sighting devices and accessories.

Grip terms

Straight: First production pistol grip. Was straight and had no notches or contours for the fingers or the hand.
Grooved: Later production pistol grip, nowstandard on all new AR-15 and M-16 rifles. Slightly thicker gripwith
a notch for the middle finger for a better grasp.

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.

The folks over at AR15. com have compiled the list below

Disclaimer: This list is correct to the best of my knowledge, however, I accept absolutely no responsibility for the accuracy of this information or for the consequences and/or damages occurring from any inaccuracies. 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.

Olympic Arms (Continued)

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:

  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.

Professional Ordinance

All are post ban (including all of the pistols).
