The Troy Industries HK-Style Front Flip-Up Battle Sight with Tritium is a reliable backup optic for AR-15 rifles that keeps you in the fight when your primary red dot or scope fails. Built for shooters who demand durability and speed, this aluminum-bodied sight combines proven HK ergonomics with Troy's rugged design philosophy. The distinctive globe-shaped front post aids fast target acquisition under pressure, while the tritium insert provides precise shot placement in low-light conditions without batteries.
Flip-up sights mount to your AR-15's handguard accessory rail and stay secure thanks to heavy spring pressure and dual locking detent balls—they won't drop when you don't want them to. A spring-loaded button on the base lets you retract the sight cleanly when you need a clear sight picture down a primary optic. At just half an inch tall when folded, it stays out of the way and won't snag on gear or brush. The M4-type post is elevation adjustable in half-MOA increments so you can fine-tune your zero.
Troy engineered these sights to mount on standard military or commercial Picatinny rails without tools beyond a flathead screwdriver—no proprietary mounts, no fiddling. Protective ears shield the post and aperture from impacts and rough handling. Because there are no protruding knobs or levers, the sight profiles low and won't catch on your kit when moving through tight spaces or dense cover.
Whether you're building a duty rifle, a competition backup system, or a general-purpose AR that needs redundancy, the Troy HK-Style delivers the dependability serious shooters expect. The tritium insert ensures you can aim and shoot in darkness or overcast conditions without relying on ambient light.

Yes. Troy designed these flip-up sights as backup optics that sit lower than most primary mounted systems, allowing your main sight to coexist on the upper receiver. When deployed, the HK-style post and aperture position at the same height as standard factory sights, giving you a familiar sight picture if you need to transition to iron sights.
The front sight clamps directly to handguard accessory rail on the same plane as a flattop receiver. It uses a standard clamping base that mounts to any military or commercial Picatinny rail with just a flathead screwdriver.
The sight flips up easily and locks securely in the deployed position via spring pressure and two locking detent balls—accidental bumps won't drop it. To retract it, press the spring-loaded button on the left side of the base.
Yes. Tritium is self-illuminating and requires no batteries or external power. It provides a faint glow in darkness and low-light conditions for aiming, though it is not as bright as an active red dot and works best when your eyes are adapted to lower light.
