For the training I've done with an AR the "dot" sights are faster than irons.
At 15 yards and in the EOTech beats the Aimpoint dot.
At plus 25 yards, maybe 35 yards....the Aimpoint beats the EOTech for me.
Reason for my old eyes, the view through the EOTech is larger and quick. However, at "distance" as dictated by how accurate a shot I have to make, when I really have to focus and aim on something more than a close center of mass or head shot then I get quicker and better hits with the Aimpoint.
Both fine sights. For me, it depends on the application. Certainly beyond 35 yards I prefer the Aimpoint. However, you can still make accurate shots with the EOTech at distance but I need to dial down the light intensity and take more time to make the shot. On the same range and barricade as shown on the Rapid Fire show at distance to pick either the Kris or Thompson I made those same shots pretty quick with an EOTech....would have been quicker with a Aimpoint....that, by the way, is a 75 yard distance shot on small poppers they made on the multi-level barricade with window.
