Built for hard use and fast target acquisition, the TROY Rear Folding Battle Sight Di-Optic AP (DOA) – Dark Earth (Model SSIG-DOA-RFFT-00, also seen as SSIGDOARFFT00, UPC 812699011249) is a premium low-profile, flip-up rear iron sight designed for shooters who want a rugged, dependable backup aiming system that deploys quickly and holds zero. Whether you’re upgrading a duty carbine, refining a training rifle, or building a reliable AR-platform setup, this TROY folding rear sight combines proven durability with a distinctive Di-Optic Aperture (DOA) concept for intuitive sight alignment.
Battle-Proven Folding Rear Sight Design
When your optic is down, your irons have to work—immediately. The TROY Rear Folding Battle Sight is engineered as a true backup iron sight (BUIS) that stays streamlined when folded and snaps into action when needed. Its folding format helps keep your rifle profile clean and reduces snag points, while still delivering a sight picture that’s fast to pick up and consistent across repetitions.
Key advantages of a folding rear BUIS like this include:
Low-profile stowage to minimize interference with optics and accessories
Rapid deployment when transitioning from primary optics to irons
Reliable mechanical alignment designed to maintain repeatable performance
Ideal pairing with a front folding sight for a complete iron-sight system
Di-Optic AP (DOA): Fast, Natural Sight Alignment
A major highlight of this model is the Di-Optic AP (DOA) configuration. In practical terms, DOA-style rear apertures are designed to support quick, centered alignment and help the shooter’s eye naturally find a consistent sight picture. For many users, that means faster alignment in dynamic conditions—especially when speed matters and you’re moving between targets.
If you’re searching for terms like “TROY DOA rear sight,” “di-optic aperture rear iron sight,” or “fast acquisition folding rear BUIS,” this is the standout feature that differentiates the DOA version from standard aperture-only designs.
Dark Earth Finish: Match Your Build, Reduce Visual Contrast
The Dark Earth finish adds more than just style. Many shooters prefer earth-tone components to better match common furniture and accessory colors, or to reduce stark contrast against the rifle’s overall palette. The result is a cohesive, purpose-built aesthetic that looks right at home on modern builds.
