I have a new friend, my PC Carbine. I mounted a see through .75 inch riser and looking through it to acquire my front sight looks like a house of mirrors. The riser is a UTG and its is very shiny in the see through tunnel. Anyone have a fix for this. I tried spraying flat black paint down the tunnel, then tried painting it with a dull coat enamel. This did not work out well. I would surely appreciate any help I can get on this. Thanks all.
