1959 to 1989
I can say that the A prefix was added to the serial number in 1977.The last nylon 66 rifles were made in 1987.So your rifle dates from 1977-1987.
Check the date code on barrel ;) There's information on the Remington Society of America, check related links.
My nylon 66 has no serial number, how do I find out what year it was made? <><><><><> Rifles and shotguns made prior to 1968 were not required by law to have a serial number. However, on the left side of the barrel, right at the receiver, you may find a 2 or 3 letter code. The Remington Collector Association website has a chart to decode the letters for the month and year that a rifle was made.
about 1978. give or take a year, but no sooner than 1977
No
it looks like in the blue book that the mod.# is nylon 66
There is a video on how to assemble and disassemble a nylon 66 on youtube.com
They month and year can be determined by the barrel code, all the details can be found on the Remington Society of America here: http://remingtonsociety.com/rsa/questions/barrelcodes (will be between 59 and 89)
Remington.
Can't be answered without the serial number.
Purple wasn't a Remington color.
