There's a date code stamped on the barrel. See related links for information on the Remington Society of America.
The barrel code stamp will tell you, see related links.
The Remington 1100 with the serial number M523669V was manufactured in 1970. The "M" prefix indicates that it was produced during the era when Remington was using letters to denote the year of manufacture, and the specific serial number falls within the range for that year.
