I have for sale a used but in great shape NF 5.5-22X50mm model C505, MOAR-T & ZeroStop. The glass is perfect and scope functions flawlessly. It does have very slight ring marks. I tried to capture them in the photos but they are so faint they barely show. It also has a small rub mark on the bottom of the turret housing which is shown in the photos. The bottom of the rubber bikini cover on the adj lens has be trimmed to clear barrel. If you have any questions let me know.
