The XS Sights Big Dot Tritium Front Sight provides a clear, low-profile aiming reference for shotguns with a bead mounted directly to the barrel. The sight combines a reflective white outer ring with a tritium center vial to improve visibility in reduced lighting. It is designed to glue over an existing bead and includes a conversion bead for certain Mossberg models. This is a standalone front sight and is not compatible with rail or ghost-ring sight systems.
