Wow! That is some mighty fine shooting with iron sights. Wish i could do as well with a 1X scope. You confused me at first, calling them 'closed' sights open sights. Matters not what you call them, only matters how you shoot, using them! It would be hard for me to shoot game 150-175 yard with a 1X scope. Evidently your eye sees the front sight pretty darn good.
