Historical Context & Novelty
Introduced in 1959, the Nylon 66 was one of the first widely sold polymer-stocked rifles in the world. -
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 Zytel 101
. Zytel is DuPont's brand name for nylon resins. 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.
