Black Gold Sight
 

I just got a Black Gold Flashpoint Red Zone sight. As soon as I mounted it and looked through the peep, it noticed that the pins were not all lined up in a vertical line. When I was sighting-in, my arrows would not land where I aimed on the horizontal axis, as I aimed with different pins.

Is it common for the pins (on any sight) to not be in a precise vertical alignment?

Thanks, Ed
