A very faulty assumption. If you managed to get a box that was "factory fresh" you MIGHT get a scope that's optically centered. If it's passed through any other hands (especially a Dealers) you can almost bet those knobs have been played with.


I just use a mirror and center up the adjustments in less than a minute. Dial the parallax setting to minimum, put objective against a mirror in a well lit room, then just adjust windage and elevation until the two crosshairs you see merge. No need to "spin test" or any other time consuming method.

If you install a new scope and have to make big changes when bore-sighting you can pretty much bet that the mount holes aren't drilled properly. One cure is to have a gunsmith re-drill and upsize the screws to 8-40 from 6-48. Also the Signature "Tactical" rings (much heavier than standard) will help. Personally I prefer to NOT use band-aid's so I re-Drill.
