I have a dumb question about Nikon's customer service. I have a 3-9X40 Buckmaster that is only about 4 months old. I dropped my gun the other day and now when I turn the magnification ring it sounds grainy, like there is sand in it and I saw a little grease type material near it. I know this is my fault, but does anyone have any experience dealing with Nikon on a issue like this? The salesman I bought it from did not like dealing with Nikon and tried to push me to a Bushnell 3200 Elite. Primarily due to the Bushnell lifetime warranty and customer service reputation.
