The trick to using most red/green dot non-magnified optics, such as the EO-Tech, is to train yourself to shoot with both eyes open...Focus on the target hit space with both eyes and bring the firearm/optic into line with your vision...
Once you get used to shooting that way, it's one of the fastest short to mid range sighting systems going...
With a little practice, at one time, I could draw. or place, button sized bulls eyes on a man sized silhouette target and hit each of them in a very short time..Same was true for moving targets moving at six feet per second across my line of sight...
