Re: remington 700 serial number?? Please!!
Remington went over to 7 digit serial numbers in 1968 following the passage of the 1968 GCA laws. I have been told that the A prefix serial numbers appeared around 1974-75. I think the first of the 7 digit numbers started at 6,200,000.
Remington does put a date stamp on the barrel which you might find helpful, it is in letter code but the information is available online at a few different sources.
