Irons alone are proven inferior against
A reliable, large tube 1X optic with a fixed or deployed front iron sight. Rear optional or mounted and simply folded away.
For me and my mission - simple arithmetic.
For my part (like rob mentioned) I need to shoot it with the dot turned off to make sure I know where it hits at inside house distances. If the rear is mounted, then I need to zero it at 100 yards using the small aperture.
If my optic can come off quickly, I need to zero the irons with the optic off the gun. If my optic does not come off quickly, then I need to zero my irons through the optic.
More simple arithmetic.
