And as such, the post front sight provides an index of elevation that the bead front sight does not. It is also easier to see if you are canting the rifle with a flat topped front sight than with a round bead. Personally, and this might not apply to everyone, I find a wide post easier to use than a narrow one, with respect to speed and precision, precision as it applies to field shooting. The human eye is very good at determining where the center of the front post is, and I seem to be able to do so quicker with a wide post than with a narrow one, or one that tapers to a point.
