I had a Nite-eye 3-9X50 and it was doing the same thing, but when you tried to re-zero you had to give it more clicks than you should have needed to. I took it back to my dealer, they sent it back and it was faulty, so they gave me all my money back. The scope was 15 months old. Top service from Weldon Gun and Deben. I used the refund to buy a second hand Leupold from Weldon Gun, a top quality scope.
