My scope arrived in completely crushed packaging; Not Arkens fault I'm sure. The optic itself didn't seem to be damaged but my ZS set screw was missing. Functions fine without but man for $500 bucks.... The screw for my throw lever was also not to be found. And now, to make thing all worse the illumination function has stopped working, both with the supplied battery and a new personal one. I should have been on the top of things with the set screw. has anyone else had problems with their scopes illumination going out?
