A shiny front sight can be a blessing in low light, and a curse in bright light! Traditionally, the front sights were made of brass or silver( coins silver from dimes, mostly) mounted in brass, and were half moon shaped. However, if you want to have a good sight that does not move your point of impact with bright sunlight as the day goes on, file a back cut in the rear of the sight, so that it is undercut, and would reflect any light down, and not back at your eye. It may not be politically correct in some circles, but it is a fine front sight for a hunting rifle.
If you have to be politically correct, keep a small tube of hobby paint in both white and black enamel, and daub it on as the day requires. It dries in minutes, and will chip off, or come off with any good solvent with an alcohol base.
I blacken my brass front blade for sunny days at the range. Pistol shooters also use spray cans of carbon to temporarily blacken their front sights. I have tried this, but with all the hand movement around the muzzle of my rifle, while I am loading it, the powder tends to rub off before you need it.
