XS Sights AR-15 A2 Tritium Front Sight Black Mil-Spec Green/White Outline

The XS Sights AR-15 A2 Tritium Front Sight is a mil-spec replacement front sight post for the AR-15/M-16 platform, designed for fast target acquisition in low-light conditions. The post carries a vertical tritium vial backed by a white outline ring, drawing the shooter's eye to the front sight in any lighting.

Machined from precision stress-proof steel and finished in matte black, this replacement post drops directly into a standard AR-15 A2 front sight housing. The tritium stripe front measures 0.105" across, giving a high-contrast aiming point for daylight and low-light use alike. Elevation is tuned in 360-degree increments of the post, with each full revolution delivering 5 MOA of adjustment at 100 yards to zero the rifle to the individual shooter.

This listing is for the front sight post only. A sight installation tool is included. The XS Sights AR-15 A2 Tritium Front Sight is made in the USA and installs in place of the standard A2 front sight post on any AR-15 or M-16 pattern rifle.
