I have a Nylon 66 Apache Black , great gun , very accurate .
If the stock ever breaks , call Remington and they will give you a New 597 because the rifle is Garanteed for Life .
Here is some good history info .
Tom Frye
In October of 1959 in Reno Nevada, Tom Frye, a professional and championship skeet and trap shooter for Remington, set out to surpassmarcot_b.tif Topperwein’s world record. Frye used three Nylon 66 rifles and shot for 13 straight days, 8 hours a day at a pace of about 1,000 shots per hour . When it was all over he had only missed 6 times out of 100,010 for a new record of 100,004 two and a half inch square wood blocks. The rifles had only been cleaned three times in the 13 days. Interestingly, Remington put one of the wood blocks from the record into each of the boxes of the newly shipped rifles. I would guess those would be the holy grail for Nylon rifle collectors if one could be found and verified.
Frye was the last of the trick shooters employed by a major firearms company for several decades. Besides his wood block record, he held a number of clay target records as well. I remember seeing him on the Mike Douglas talk show in 1975 shooting thrown objects out of the air. Imagine seeing popular trick shooting on a national syndicated talk show today! Frye died in 1982 at the age of 66.
