The Truglo Long Bead fiber optic sight (brand part no. TG947ERM) is a CNC-machined metal bead built as a drop-in replacement for the factory bead on a range of over/under shotguns. It’s fitted with a bright red 0.078 in. fiber optic rod that gathers ambient light for a sight picture that stands out fast against most backgrounds. This version uses a 3mm mounting thread matched to Browning, Caesar Guerini, Charles Daly, Franchi, Mossberg Reserve O/U, Weatherby, and Winchester over/under shotguns. As a long bead, it sits taller than a standard factory bead, giving a more visible sighting reference for clays and upland hunting.
