I have, mostly on hunting rifles used in low light conditions. Formal target range, daytime, aligned right angle to the suns path, black front generally the best. Some ranges will throw you, backstop east sun rising in your eyes the worst.

Adjusting the rear arpeture as light changes is a key. Open as much as possible closing smaller to sharp front focus while maintaining adequate light on the target. Matches  I adjust the rear every relay, sometimes every shot. Silhouette targets, no defined point of aim it's essential

I use fine post and bead front sights and take a single hair brush and put a drop of day-glo orange paint on the bead.

i only have a single hair left and am not painting with it   art
