Truglo 12-20 ga Glo-Dot II Universal

The Truglo 12-20 Gauge Glo-Dot II Universal is a snap-on fiber-optic sight designed specifically for plain barrel shotguns in 12 and 20 gauge. This compact aiming solution installs directly over your existing front bead sight, providing a bright, high-visibility aiming point without permanent modification to your barrel. The design delivers the fast target acquisition demanded in upland hunting, waterfowl pursuits, and defensive shotgun applications where split-second sight picture clarity matters.

The 0.078-inch fiber diameter creates a fine aiming dot that gathers ambient light efficiently while maintaining an extremely low profile that won't interfere with barrel aesthetics or handling. Construction is ultra-tough, engineered to withstand the recoil cycles and field conditions typical of shotgun use. Installation requires no gunsmithing—the Glo-Dot II simply slides over your bead, achieving perfect alignment without tools or permanent alteration. The universal fit accommodates most plain barrel shotgun configurations, making this an ideal upgrade for hunters and sport shooters seeking improved aiming precision on firearms that traditionally ship with minimal sighting equipment.

This sight appeals to upland hunters, duck and waterfowl enthusiasts—Truglo's endorsement by Ducks Unlimited reflects real adoption by the waterfowl community—and shotgun owners who demand reliable aiming aids on classic or modern plain barrel guns. Whether you run a classic side-by-side, an over-under, or a modern tactical shotgun with a plain barrel, the Glo-Dot II fills the gap between factory bead sights and more complex optical systems. The low-profile design keeps your sight line uncluttered while delivering the glowing dot visibility that fiber-optic technology provides in all lighting conditions, from dawn patrols to overcast days.
