TruGlo TG231AR1 Tritium Front Sight AR-15 Green/White Outline Black

The TruGlo TG231AR1 is a self-illuminating tritium front sight purpose-built as a drop-in replacement for the standard A2 front sight post on AR-15 platform rifles. It is machined and assembled in the USA from a rugged CNC-machined steel housing protected by TruGlo's nitride Fortress Finish in black, giving it the durability to stand up to hard use and harsh field conditions.

A self-powered green tritium lamp sits at the heart of the post, encircled by a high-contrast white outline ring. The tritium provides a steady, glowing aiming point in low-light and nighttime conditions with no batteries or light exposure required, while the white ring frames the dot for fast, intuitive target acquisition during the day. The TG231AR1 also includes an integrated windage drum for precise adjustments at the bench. The drop-in design installs directly in place of the factory front sight post on AR-15 rifles equipped with a standard A2 front sight base.

The TG231AR1 ships with a dedicated adjustment and installation tool so you can swap it on at the bench without a trip to the gunsmith, and it is backed by TruGlo's Tru-Care lifetime warranty. Front sight only; rear sight is not included.
