Log #6285 Black Diamond. Comes with original box. 

The Remington Nylon 66 Black Diamond is a distinctive and highly collectible variant of the iconic semi-automatic .22 LR rifle introduced by Remington in the late 1950s. Known for its innovative use of DuPont's Zytel nylon in the stock and receiver, the Nylon 66 was among the first rifles to successfully incorporate synthetic materials, making it lightweight, durable, and resistant to weather and corrosion. The Black Diamond version, produced in limited numbers, features a striking all-black finish with diamond-shaped checkering on the stock, setting it apart from other models like the Mohawk Brown and Apache Black. Renowned for its reliability, accuracy, and virtually maintenance-free operation, the Nylon 66 remains a favorite among rimfire enthusiasts and collectors alike.
