Buy a set of Testor paints a try a few colors, a drop on a toothpick on the front sight will do you. I ended up with fluorescent pink rose on most of my sights because they show up best against the back ground I shoot against both summer and winter and it made a huge difference. Your eyes or your shooting background may prefer another color that's why you want the box of 8 colors.
I use them on my fishing lures too so the paint won't go to waste.
Good intentions will always be pleaded for any assumption of power. The Constitution was made to guard the people against the dangers of good intentions. There are men in all ages who mean to govern will, but they mean to govern. They promise to be good masters, but they mean to be masters.
