Look up "occluded eye gunsite" I have always had standing front and rear irons in line with my red dot, they are in a different plane of focus and don't get in the way. I sometimes see these threads about the size of the window and how it occludes your view, that's all bull, people who make those threads aren't shooting a red dot the right way. The exception is if ypu have limited vision, for example my dad's eyes cannot work together, so in that case they might have a point. But with two good eyes and the right sighting technique, both your eyes open and focused on the target, your brain fuses the two images together, and irons, viewing window sizes, even a front cap on the red dot, don't matter.
