Re: reflex sights/red dot sights - help
ACOG is the closest thing, but not technically a reflex sight. Maybe a 1-4 short dot since they seem to be the standard of 'daylight practical' illuminated scopes. (also see SWFA 1-4 though it is not for sale yet)
The nature of how reflex dot sights work is that the 'dot' is projected and reflected back, not a suspended reticle like a traditional scope. So when the 'dot' is off you just look straight through the otherwise clear lenses.
