The XS Sights Big Dot Tritium front sight provides a large, high-visibility aiming point for shotguns by combining a tritium insert with XS Sights’ photoluminescent Glow Dot for improved low-light visibility. The convex Big Dot geometry increases surface area to intensify the charge of the Glow Dot and speed sight acquisition. This front bead is intended for plain-barrel shotguns that accept the specified bead diameter and installs using any two-part epoxy. It is a standalone front sight and is not designed to interface with ghost-ring rear sight solutions.
