Ameriglo surprise configuration - AmeriGlo I-Dot Night Sight Set

I bought several sets of Ameriglo Spartan Tactical Operator sights in three dot configuration from Optics Planet over time. I purchased these I-dot sights to: a) try something different for my new Gen5 26; and b) save a little money versus the Spartans. I like this system much better than traditional three dots for night sights usage on a quick target acquisition basis. Also, the bottom dot is mostly invisible for daytime shooting, as the rear sight appears blacked out, much like the Hackathorn sights. I must say, I was pleasantly surprised by the functionality of these sights. They are great in all light conditions. Also - Ameriglo quality is excellent. Installation is easy with the right tools (sight pusher). The price was great at about $80 delivered with taxes. Delivery was very quick and efficient. I like these sights very much and would definitely buy them again.
