I was out target shooting when my rifle took a bad fall and landed on the scope M223 3x12x42 6 months old. Happened when I was in load development stages. After a few more trips to the range my moa never got better than 1.5 or 2. I can shoot sub moa. So It got me thinking that maybe the scope got tweaked when it hit the ground. I called Nikon told them what was going on. They said they'll look at it. Well almost 3 weeks later the brown truck came with my scope. My new scope! they replaced it, can't believe it. Looks like a newer a model since the turrets are completely different. But in a good way. The paper work doesn't explain why they replaced it. Just that they did. Points for Nikon.
