I went to a gun show in Little Rock this past weekend and was blessed with a trade in which I got a Mini 14 and a bunch of mags. I'll see about posting pics. later. Anyhow, I went to look up the serial number and found that it falls before the "production began with" for the first year of the 181- series (181-02XXX). How is it possible? Is it rare for Ruger to do that sort of thing? Could it be a collectors item? Thanks,sharps.
