I just bought troy bios rear sight ander after initial inspection discovered a potential problem. The apperature is positioned opposite to the way it is in my dd fixed rear. On the dd the flat part is away from the shooter, with the concave par towards the eye. On the troy, the ""bowl" is toward the eye, and the flat part is towards the target. Which is the correct way? I was going to go and sight in the new sight tomorrow and would like the potential error before having to re sight again.
Thanks
