I put the skinner on my 1894 and it is hitting 6" high at 25 yds,so I need a taller front site (barrel mount). Looking at the add the tallest sight is .500", my original sight is .498" I measured from the top of the sight to the very bottom of the overall sight of the dovetail. Where am I going wrong or is there something wrong. Also what is the normal thickness 1/4" or 3/8" for hunting purposes.Thanks
