Blur on your gun is in fact, very realistic. Unless you have some specific eye condition, unlike the rest of the human species which lets your eye focus on everything at the same time. Even if you look through the ironsight in IRL it will appear blurry when looking at the target. It's basic depth perception.

You eyes irl do it for you. It would appear blurry because where you look is your focus point. So having one pre placed literally makes no sense at all.

@5sety4 it makes perfect sense because camera in-game doesn't work like an IRL eye and doesn't have a dynamic depth perception so if there's one place you'd put it, it would the one that's in the game. Also since when you're aiming IRL, you'll always look either at the tip of the barrel ( or iron sight ) to line it up with the target, and everything behind it will be blurred out.
