I'm considering changing my Aimpoint Comp M4 to a Vortex Razor 1-6. I've read you can see the dot well in daylight with the Vortex. How much speed do you lose in target acquisition of a red dot vs LPVO on low setting? I'm thinking it would be just as fast as long as I train with it. My eyes are also not quite what they used to be when I was younger, so that's why I'm considering the change.
