The Tracker II is not necessarily bore sighted. If you look on the right side of the rear sight below the blade slot, you should see a small screw used to adjust for windage.....
Have a good time sighting that in and getting ready!
For my Tracker II, in order to get the elevation set to a low level [read that profile] for the slugs I am using, I filed the front sight down a littlte [to raise point of impact]. That way I did not have the rear sight at maximum height, ready to snag on small brush or clothing at the worst moment......
