I'll second the fiber optic sights- Williams or Hi-Viz. I have a set on both of my Henry .22's and on my MKIV and love them.I'm gonna put a plug in for the Hi-Viz front sight. I put one on my 5 inch bbl GP100 and love it. It has replaceable color pipes, red, green, and white and my preference has been for the red. It really pops and shows up well.
