Meprolight USA Tru-Dot AR-15/M-16/M-4 Fixed Green Tritium Front Sight

The Meprolight USA Tru-Dot fixed front sight post replaces the factory front sight on AR-15, M-16, and M-4 pattern rifles, delivering a self-illuminated aiming solution that works in daylight, low-light, and nighttime conditions.

A green tritium lamp is embedded in the thin, cone-shaped front sight post, providing a bright, always-visible aiming reference without batteries or any external light source. Meprolight's combat-proven Tru-Dot night sights remain on and ready 24 hours a day, 7 days a week, 365 days a year, with tritium illuminance guaranteed for years of reliable service.

Installation is straightforward on the standard front sight base of any AR-platform rifle, requiring no permanent modification or gunsmithing. The sight is built on a rugged steel housing finished in black for a low-profile, snag-resistant geometry that mirrors the standard-issue front sight silhouette.

An ideal upgrade for home defense, duty, or recreational AR-pattern rifles, the Meprolight USA Tru-Dot front sight provides instant, all-light aiming capability in a fixed, battery-free package that requires no transition between day and night use.
