How can you determine manufacture date on Remington 1100 12-gauge shotgun?

To determine the manufacture date of a Remington 1100 12-gauge shotgun, you can check the serial number located on the receiver. Remington used a specific serialization system; for example, shotguns made from 1963 to 1980 have serial numbers that can be referenced against a Remington date code chart. Additionally, if the shotgun has a barrel code, that can also provide insights into the date of manufacture. Consulting Remington's historical records or contacting the company directly can offer further assistance.
