I would be interested to know how much the perceived size of the diamond front sight changes with varying sunlight.

I have tried to shoot guns equipped with the new-fangled fiber optic front sights, and I get nowhere with them. A slight change in the sunlight results in great changes in the appearance of the front sight with a corresponding change in sight picture. Mostly the error is in elevation, which can be absolutely crutial to the shot. I finally decided the "glowing" fiber optic sights are totally worthless.

I hope the diamond sight is better than that.
