The Truglo TG93B Glo-Dot II 410 Gauge Green Fiber Optic Black is a purpose-built enhancement for plain barrel shotguns, delivering a bright, easy-to-see aiming dot that snaps in place over your existing front bead-sight for quick alignment and improved target acquisition. Designed to be extremely low profile, it installs with minimal fuss and stays securely in place under demanding field conditions, making it a reliable choice for duck blinds, upland hunts, and sporting clays alike. The ultra-tough construction ensures durability shot after shot, while the fiber optic 0.078-inch core provides a crisp glow in both bright daylight and dim environments, helping you maintain focus on your target rather than chasing a sight alignment. Endorsed by Ducks Unlimited, this Glo-Dot II sight pairs seamlessly with standard shotgun sighting setups and enhances overall accuracy without altering the barrel profile or balance. Whether youre upgrading an existing setup or equipping a new plain-barrel shotgun for waterfowl, bird hunting, or clay ranges, this fiber optic front sight offers a simple, effective path to faster target acquisition and improved shot placement.
