My take on it.....

Trigger control is an important part of accuracy. Dry firing is great for this. The laser is not needed.

Another part of the equation is being able to shoulder the rifle accurately. So I believe that the act of re-cocking the rifle and bringing back to firing position is beneficial.
Do this; dry fire, cock, close eyes, shoulder rifle, open eyes and see how well the sights are lined up. You can practice without dry firing also.
If you plan on putting your skills to some utilitarian purpose such as; hunting coyotes or tactical like stuff, then this is important. Practice shouldering and u should be able to get into firing position and everything is lined up to shoot.
