Description
The XS Sight Systems Big Dot Shotgun Bead is a defensive front sight designed to replace the factory bead on vent rib shotguns. The Big Dot puts a wide, easy-to-find aiming reference on the muzzle end of your shotgun, exactly what you want when the lights are down and the stakes are up.
Each bead is built around a tritium-illuminated 0.188″ Big Dot encircled by a high-contrast orange ring. XS layers in its photoluminescent Glow Dot technology, which absorbs ambient light and re-emits it in the dark to back up the tritium, creating a sight that charges from any light source and stays visible in low-light defensive scenarios.
Machined from steel for durability, the bead drops into the existing vent rib bead mount on most vent rib shotguns as a direct replacement for the factory bead, no gunsmithing or permanent modification required. Whether you run a defensive shotgun for home protection, patrol, or tactical use, the XS Big Dot vent rib bead gives you a fast, defensive sight upgrade that works day or night.
