Please note that many rifles, particularly .22s, did not have serial numbers prior to the Gun Control Act of 1968 rifles were not required to have serial numbers on them. Remington started numbering Nylon rifles in 1967 starting with #40000-419011. In 1968 the numbers ranged from 419012-473710. The serial numbers were located on the bottom of the barrel, below and just back a bit from the front sight. In December of 1968 serial numbers were moved to the receiver cover and re-started at 2100000 and went to 2599999 in January of 1977. In February 1977 an “A” was added and the range was restarted at A2100000. These serial number series pertain to all Nylon rifles, not just Nylon 66s.
Please also note that these code letters refer to all Remington rifles including all the variations of the Nylon line.
Also note that sometimes you will find 3 letters on the barrel.It is sometimes difficult to determine which of the letters apply. Best thing to do is use the serial number trick above (w/o serial # pre 67, w/serial # post 67). Then fit the letters as appropriate.
There have been several discussions in the Forum regarding date codes and serial numbers and is a good resource for more information on the subject.
