Nikon Customer Service
I had a Nikon 2-7x scope that was about 12 years old or so, before they had they offered different models like the Monarch, Buckmaster, Pro Staff, etc. When I got the scope, there was only one model of Nikon scope available. On this year's bear hunt, we got rained on most of the time, during our week long hunt. After I got home, I discovered that the scope fogged internally.
On a friend's recommendation, I sent it back to Nikon for repair. I got their address off the Internet, and mailed the scope in for repair. It cost me $13 in shipping and isurance. In less than 2 weeks, I recieved a brand new Monarch 2.5-10x replacement.....free of charge.
Got to like that!
