Every gun I seem to mount I have a 1/4" gap between the mid and front bead. The two ways I can get close to stacked beads is to mount the gun very high on my shoulder or lean my head. Neither of which I want to do. I'm a 2 eyed shooter with my eyes parallel to the ground. I'd like to bring my POI down as it's 100% over at 16 yards. What are my best option(s) and\or solution?
