I’d heard some buzzing the last couple weeks about this, so I called Nikon for myself today.

Nikon has discontinued production of all of their riflescope lines, and will finish out distribution of existing inventory within a year. I asked what this meant for warranties, and the representative claimed all warranties will be upheld as promised. However, when I asked further - what happens if I need a repair or replacement of a warrantied scope in a certain time after parts and replacement scope inventories have run dry, the response, “we have not been provided that particular information at this time.” - which I interpret as “you’ll be SOL.”
