I just recently purchased a SA M1A and am wondering about the serial numbers. I found four of them:

1. SN- 1181xx (rifle sn)
2. Bolt -77901xx TRW Z6
3. Reciever - 72670xx-2 SA
4. Inside Reciever - 1346xx 04

Could someone please share what all these mean, I have a rough idea but would like to be clear..

Thanks in advance,

Jeff

Your receiver was made about the time you returned from Bosnia.
