I have a Mark II F on which I installed fiber optic sights.

Now I think this was a mistake, while the fiber optics are very easy to see they are also huge when compared to the iron sights they replaced. It's like looking at a ballon on the front of the rifle.

I suppose I could put the original iron sights back on but before I do does anyone have any suggestions for a replacement sight or possible lightweight scope?

My goal is to use the Mark II F to hunt small game and I want to keep it as light as possible.
