If you have a A2 style front sight and a holo sight like an EOTech, you can have your iron front sight be co-incident with the bottom of the turned-off glass in the EOtech and you have a sight system right there without batteries.
It sounds complicated, but if I had an EOTech and the front iron sight set up correctly on a rifle in front of you, you’d see instantly what I’m talking about.
I do see what you are saying there, and that does make sense. I will probably look into a hologram after I save up a bit more cash, those suckers are pricey.
I’m just going to try out the pop up sight and the iron tomorrow and see how I like those.
