The serial number on a Remington firearm is located on the left side of the barrel of the gun. The serial number on each Remington can be decoded to know the month and year that specific gun was manufactured.
The first letter in the serial number corresponds to the month of manufacturing, while the second letter corresponds to the year. From 1999 to 2001, the Remington company did not date stamp the firearms they manufactured. Due to the repeat letters in the Remington chart for decoding serial numbers, gun owners may need to take into consideration the model type when determining the manufacture date.
