The Black Nylon 66, also known as the Remington Arms Company's "Apache Black" Nylon 66 .22 LR Rifle, fired .22 caliber long rifle rimfire cartridges. Later variants of this model could fire .22 short, long and long rifle rimfire cartridges.
The Nylon 66 was manufactured by the Remington Arms Company in three colors: "Mohawk Brown," "Seneca Green" and "Apache Black." Remington also produced variants of these with minor modifications and in limited production special editions from 1959 to 1987. Nylon 66 is also known as Zytel, a DuPont-manufactured synthetic from which nearly the entire gun is constructed, making it one of the world's earliest "plastic guns."
