Bushmaster Serial Number List
Bushmaster Pre Ban Serial Number Date

The serial numbers listed, except for 1963, 1969, 1970, are the serial number at the first of the year. NOTE II: The 1969-1970 downturn (highlighted in purple) in production numbers is due to Colt withdrawing the AR-15 from the market temporarily to fix the 'hammer follow-down' issue (the gun could fire full-automatically - erratically - if. Trying to figure out what AR15 I have, its a Bushmaster MOD. XM15-E2S and its stamped CAL. MULTI It shoots 223/5.56 Ive read that all Bushmasters serial numbers start with either a BFI or IL prior to the numbers,But mine starts with ARA.

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, mostly from the Internet.

ALL SERIAL NUMBERS SHOULD BE VERIFIED FROM THE MANUFACTURER PRIOR TO ANY PURCHASE OR ASSEMBLY.

It should be clearly noted that it is a felony to possess a Post-Ban (newly assembled after Sept 13, 1994) assault weapon. Please note that BATF has ruled that 'Pre-ban' and 'Grandfathered' are two different things. A Pre-ban lower is only grandfathered if it: 1. was a complete rifle prior to 9/13/94; 2. possessed two banned features (pistol grip and CAR stock assembled); or 3. was part of a complete weapon kit, either assembled or not. This list does not discern between 'Pre-ban' and 'Grandfathered' as it is very nearly impossible to find that detail of information.

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. Finally, BATF has allowed some pre-ban damaged to be replaced with post-ban lowers with numbers outside the ranges given below while retaining the grandfathered status. They will send a letter documenting this and allowing the original manufacturer to proceed with the replacement.
