Hi folks, I recently purchased a pair of used Nikon Rimfire Prostaff scopes from an individual ,one has superb glass The second for lack of a better word just isn’t as bright and the crosshairs seem very light ,also need to move your eye quite a ways back to get a complete full view , The seller is defending it like there’s nothing wrong with it ,more correctly nothing is right with it . Is Nikon still doing repairs?
