gallatin, if my memory serves me right, Williams recommends a front sight with .450" height with the WGRS. You can buy a fine gold bead replacement from Williams at this height. Or, you can buy an excellent front sight from XS sight systems (formerly Ashley) with this height. The XS front sight is a most excellent sight. If there is light in front of it, it is a clearly defined black front post. If the light is behind it, that white stripe up the middle shows up beautifully. It is at just the right angle to fully exploit this property. By all means, get a new front sight.
