For anyone who doesn't know, iron sights are the small sights atop, or in the case of an aperture sight, in the back, of a weapon that allow you to aim. This thread is about the fact that 90% of the weapons in Halo 3 do not have iron sights. Please, unless you give a ****, keep reading. It's not immersing, it's not funny, it's just the product of my bored mind. Look, I'm bored, it's raining, I'm hungry, and I decided to write this.
