I guess things changed when Bushmaster moved, because I bought a preban Bushmaster lower on Gunbroker in 2008, I asked for the serial numbers and called Bushmaster asked if it was indeed pre-ban and if it was shipped from the factory as a complete rifle. The nice lady whose name I can't recall said it was and sent me a letter stating so. I do notice newer Bushmaster models tend to have properly staked bolt carriers, and the older ones tend to have a shallow staking on the bolt carrier. FYI, my bushmaster had a serial of L52XXXX which I bought around 2010/11 as my first AR rifle. I do know it's when they were taken over and no longer 'Bushmaster.' Event Date: Event Description: 2006-08-03: SN ASSIGNED FOR SECT 66A APPL FROM IB: 2006-08-03: NEW APPLICATION ENTERED IN TRAM: 2006-09-14: ASSIGNED TO EXAMINER. Bushmaster Firearms Serial Numbers; Bushmaster Preban Serial Number; I talked to Bushmaster and the date of manufacture was 3/11/94. The assult weapons law was passed on September 13, 1994. So the gun is actually a pre-ban weapon.

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, 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.
