We need more info to help you out.
1. Are you mounting it yourself? Pretty easy to do
2. Will it be bore sighted or not? Not necessary but it helps
3. The distance you want it sighted in.
4. Gun, scope, caliber, bullets. Shotgun, rifle, pistol??
5. Will you be using a benchrest and sandbags or equivalent, or just shootin' freehand at a target?
Answer these questions and I'm sure plenty of guys would love to help you out.
6. Oh last, but not least not all of us speak "Drawl". What do you mean by fixing? Is your scope broken and you are trying to fix it?
