Hello, has anyone had troubles with their tech-sight being off center? I recently purchased one for my sks after reading many people sing its praises saying it is a great upgrade to increase accuracy. However, when I mounted it sits very off center to the right. Is this supposed to be this way? How do you fix it? this is a picture of the sight. I don't want to take it to a gunsmith if I don't have to since they charge an arm and leg just check it out.
