The TruGlo Fat Bead (part no. TG948ER) is the largest-diameter fiber-optic bead TruGlo makes for a shotgun or rifle front sight, built as a direct-thread replacement on a 3mm sight base. Truglo tunes this version in red for maximum contrast against most backgrounds, making it easier to find fast on a moving target than a factory bead. It’s a simple thread-in upgrade for anyone whose factory bead has faded or who wants a brighter sighting reference.
