I use my borderlands scope, It's probably not the best, but it looks nice and has pretty good accuracy. So it's the best in my opinion ;)

@Flame: Galaxy's kind of sight is the type of sight that I use as well. I can rack up a lot of kills with it since it's not obstructive.

A good criteria for an iron sight is to be precise, simple (if possible), and it should give you clear view of what you're aiming at. (If your peripheral sight is clear as well, that's better)

Here's what I use- old school sights, just about the smoothest transition from hip to aiming possible. Link.

If I didn't use my own sights though, I'd definitely use General Joe's pack.

well give meh the link then

What Legox50 said.

There is one that Lexsym made a while ago that I still use. It's a very simple crosshair with a dot in the center and a transparent peripheral area. I've been accused of aimbotting countless times because of it.

Best sight? Some kind of simple translucent cross-hair with minimal obstructions to view...

I use this
