I took mine to the range and shot it using the sights to start with. Once I was satisified that the sights were hitting to point of aim, I turned the laser on and used it.
After a little minor adjustment, the shots hit where the laser was pointing which is also where the sights are looking.

A bore sighter is used to get you on paper, not for doing your acutal zeroing. Take it to the range, shoot it and zero it.
