I picked up this morning a Remington Nylon 66 Apache Black at the Richmond (VA) gun show. It had attached sling swivels front and rear. The seller advised me that as far as he knew they were installed at the factory. I always thought that sling swivels were available for the Nylon rifles but as an aftermarket purchase. And even then you had to be careful you bought the right attaching screws because of the nylon stock. Can anybody clarify/confirm factory installed sling swivels. The ones on my rifle look good and are functional but I did not know Remington put some swivels on some rifles. The date codes make this rifle a 1965 model. Membership comments/thoughts would be greatly appreciated. Thanks.
