I'm toying with the idea of night sights. It seems that even a cheap set of night sights runs about $80. I'm going to try to make my own by drilling a spare set of sights and inserting a piece of fiber optic cable. Has anybody tried using anything but green, red, or orange? I'm going to see how a clear cable functions since its so much cheaper. Has anybody tried different kinds? Also to anybody who has done this, where did you buy your fiber optic rods?
