I was reading an old (well, 6 - 8 months old) gun magazine that a guy brought into the office the other day. In it was an article about AMU accurized M-16's used as designated marksmen weapons for the 3rd Infantry. In it, they mentioned that the AMU (Army Marksmanship Unit) in the past had built National Match M-14'a and M-1 carbines. I have never heard of a National Match Carbine. Anyone got any info?
