When the weapon is fired, the bullet 'climbs' (actually, a bullet DROPS from the bore line from the moment it first leaves the barrel, but the bore is tilted upward slightly so the bullet is physically traveling upward for a short distance), crosses the sight line, reaches its upward peak (the peak of the 'mid-range trajectory'), descends to cross the sight line a SECOND time, and after that it's all downhill. On a normal weapon, the sights are mounted above the bore line and are adjusted to look slightly down with relation to the bore line.
There is only one distance where the bullet path will coincide with the laser. There are two adjustment screws located on the laser housing (elevation and windage).
