Posting for a friend from another forum. He is hunting in snow and is having issues with the photocell/sensor on his sight getting extremely dark and then when sun goes down, it wont lighten back up. Says he has spoken to MBG and they admitted there was an issue with this but offered no solutions. I asked him about a sight light and he stated they are illegal in Idaho. Anyone ever had this issue with MBG sights? If so, how did you correct it?
