The above chart shows the approximate first serial number shipped for the indicated year. This number should be used as a point of reference only. It is not necessarily the very first serial number shipped, but it can be used to determine the approximate year your Ruger firearm was shipped.

Ruger does not produce firearms in serial number order. There are occasions when blocks of serial numbers have been manufactured out of sequence, sometimes years later. Also, within a model family the same serial number prefix may be used to produce a variety of different models, all in the same block of serial numbers. And in some cases, models may be stored for a length of time before they are shipped.

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 360-459-7940

  • 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.

No complete guns were sold (again, unverified info).
