TROY Industries M4 Folding Front Sight with Tritium – Black

The TROY Industries M4 Folding Front Sight with Tritium provides a self-luminous aiming point for low-light target acquisition without batteries or external power. The tritium insert glows continuously for years, making this folding front sight ideal for backup iron sights (BUIS) on AR-15 and M4 platform rifles where rapid transition from optics to irons may be necessary in compromised lighting.

This sight mounts to any MIL-STD-1913 Picatinny rail and folds flat when not in use, allowing unobstructed optic view. The spring-loaded mechanism deploys with positive tactile feedback. Constructed from aircraft-grade aluminum with a hardcoat anodized black finish, it withstands hard use and maintains zero. Standard M4 front sight height for co-witness with most AR-15 rear sights.
