Troy Industries Tritium Folding Front Battle Sight M4 - Black

The Troy Industries Tritium Folding Front Battle Sight M4 is purpose-built for AR-platform users who demand reliable target acquisition in low-light and no-light operational environments. This front sight serves as a primary aiming reference or co-witness complement to mounted optics, combining proven battle-sight geometry with self-illuminating tritium technology.

Manufactured from aircraft-grade aluminum and stainless steel, the Troy Industries folding front sight delivers durability and minimal weight. The tritium sight dot glows independently without batteries, providing immediate visibility in complete darkness—a critical advantage during night operations or emergency response scenarios.

Users benefit most in duty and defensive contexts where backup aiming capability is non-negotiable. The folding design allows rapid stowage when using a primary optic, and the sight folds flush to minimize snag points during tactical movement. This sight mounts to M4 and AR-15 receiver-height rail systems and will not function correctly with railed gas blocks that sit above the receiver plane—a critical compatibility consideration during installation.
