I have four Remington Nylons 66 Mohawk Brown 10-C, Black 66, Green 77, and Brown 66, 22 Long Rifle all in good and some in near perfect condition.
In the 1950s, Remington Arms was interested in designing a rifle that was cheaper to produce. After analysis, engineers determined that there were savings to be found in the production of the receivers and stocks of rifles. Thus Remington asked chemical engineers at DuPont to come up with a plastic that could replace both the wooden stock and the receiver. The specs given to DuPont called for a material that could be formed into any shape desired but that also had a high tensile-impact and flexural strength. After some research, DuPont came back to Remington with a compound they called Nylon Zytel-101. Zytel is DuPont’s brand name for Nylon. This compound was ultimately used to produce the stock and receiver. After the Nylon 66 proved to be successful, Remington also marketed a series of bolt action and lever action rifles using Nylon stocks. The largely synthetic construction meant that the Nylon 66 could operate without any added lubricants. This made it popular in arctic regions, and indeed there have been many reports of indigenous peoples killing large animals, such as moose, with a .22 LR fired from a Nylon 66. Some have speculated that the light weight of the gun could potentially cause substandard accuracy in the field, but this does not seem to be a complaint from Nylon 66 shooters. The Nylon 66 was fitted with leaf sights as well as a grooved receiver that could accommodate a mount for a telescopic sight. All this in good to near perfect conditon.
