XS Sights AR-15 A2 Tritium Stripe Front Sight .278

The XS Sights Tritium Stripe front sight is an AR-15 A2 Mil-Spec replacement designed to provide a visible front-sight reference across varied lighting conditions. It features a .278-inch post, a vertical green tritium vial, and a white outline for contrast.

Made in the USA, this front sight fits AR front sight housings with the front sight detent positioned at 3, 6, or 9 o’clock. It does not fit ARMS backup sights because the blade is too long to allow the tower to fold into the down position.
