I currently havea Copper John Dead Nuts Hunter that I absolutely love. It's been a great sight, very rugged and very dependable. However, like the knucklehead I am I just ordered a Dead Nuts 2 Pro w/micro adjust. I just got confirmation that it shipped today, so as soon as I get it in I'll make sure I post my thoughts. From what I saw at the ATA Show they look like great sights, and from what they've told me on the phone the fiber optic pins are made of a new, more durable fiber optic material so prevent them from becoming to brittle incold weather.
