TruGlo Long Bead Universal Shotgun 3mm Green Fiber Optic Front Sight

The TruGlo Long Bead is a universal shotgun replacement front sight designed to upgrade any shotgun fitted with a 3mm threaded vent rib bead post. It is CNC-machined from steel with a durable black finish, giving it a slim, snag-free profile that sits just above the rib for fast, intuitive target acquisition.

A bright green fiber optic collects ambient light to deliver a vivid aiming point in low-light and bright conditions alike. The fiber measures 0.078 in in diameter and 0.5 in in length, producing an extended, distinct bead that provides a clearer sight picture above the vent rib than a standard factory bead.

The universal fitment package includes multiple mounting screw sizes so the sight installs on a wide range of shotguns with a 3mm vent rib bead post. Whether you are replacing a factory bead or upgrading to a brighter, more visible aiming point, the TruGlo Long Bead universal shotgun front sight is a straightforward visibility upgrade for any shotgun.
