Nylon 66s in the author’s collection include a Bicentenial (just below the boxed 66), Seneca Green just below it.The 10C represented the 10 shot “clip” which was brought out to compete with rifles like the Ruger 10/22.Both the 77 and 10C were made with brown stocks and blued metal. Remington made a version of the nylon rifles for K-Mart in 1987-89.In addition, there was a “150th Anniversary” model produced in 1966 and a “Bicentennial” model in 1976.Both had brown stocks and gold etched, blued receivers.
The Apache 77 is truly a low-key rifle in that it is sans the white diamond and white fore/butt/pistol grip cap spacers found on other nylon rifles. The magazines for the original 77, 10C and Apache 77 are inner changeable.
