The XS Sights Big Dot Tritium front sight provides an illuminated aiming reference for shotguns with a bead-mounted front sight. A white outer ring reflects ambient light for increased visibility, and the center tritium vial glows green in low- to no-light conditions for 24/7 use. The sight epoxies over the existing front bead and is designed for bead diameters in the range noted below; installation may require opening the bead hole by drilling and tapping or replacing factory beads on some shotguns.
Key Specifications
- The sight epoxies over front beads that measure 0.120–0.140 inches in diameter.
- The outside diameter of the Big Dot measures 0.188 inches.
- The center vial contains tritium for low- to no-light visibility (glows green).
- The surrounding ring is a white reflector to aid visibility in ambient light.
- Installation uses adhesive over the existing bead; may require drilling and tapping to enlarge the bead hole.
- The product is a stand-alone front sight solution and does not work with rails or ghost ring combinations.
- Kits include a Mossberg conversion bead where applicable, since some factory beads may be incompatible.

Designed to improve sight acquisition and low-light usability without adding rails or complex mounting hardware, the XS Big Dot Tritium front sight offers a simple upgrade for compatible shotguns. Its combination of a reflective white outer ring and a glowing tritium center provides a clear, repeatable reference in a wide range of lighting conditions while remaining compact and unobtrusive.
