Nylon 66

How can you tell how old a Remington Nylon 66 semi-auto .22LR is?

Yup. On the left side of the barrel just ahead of the rear site there should be 2 letters stamped on the barrel itself. Let us know the letters and we can convert it for you or search this forum for the codes yourself. If its Seneca Green , you better just send it to me and save yourself the hassle.
