Hi akraven,
I have no personal experience with Sightron scopes, but I have heard pretty good things about the Sightron "II." Specifically, I have a friend of mine that has one on a 7mmSTW and its optics are good, its adjustments are precise, and its tracking is very good. Last month I was at the shooting range and a shooter also had a Sightron II. Again, tracking was good and his groups were sub-inch in his rifle (a .300 Ultra Mag.) Sightron now has a Sightron III, which is not that much different than the II model.
