Truglo Tritium Front Sight for AR-15, White

The Truglo Tritium Front Sight (brand part no. TG231AR1) is a white tritium front sight post built to replace a standard AR-15 A2 front sight, giving the shooter a self-illuminating aiming reference that glows without needing any light exposure to charge. Because tritium is a true light source rather than a fiber optic that depends on ambient light, it performs the same in a lit room or total darkness, which makes it a genuine low-light upgrade rather than a daytime-only accessory. It’s compatible with AR-15 sights using A2 front sight posts and ships with the adjustment and installation tool needed to swap it in.
