I just had my AR slicked up and a Reflex II slapped on. I really like it. It has the polarizing filter which does really help with the light issue. I generally leave mine on all the time so far. It is definitely a rugged little booger. Don't ask me how I know!!
I also really like the triangle over the dots so prevalent in optics these days. My eye really picks up the triangle. Could there be somehting better out there?? Possibly. But, I am very happy with what I have. So I am not going to mess with it.
Personally, I think everyone is a bit trigger happy to pick at the Reflex because certain military units chose an Aimpoint over it.
Well, WHOOHAH!!
I think I will stick with what works for me.
