Trijicon ACOG ECOS 4x32 Green Crosshair 5.56 Scope+RMR FDE TA31-D-100554

Key Features

• Dual Aiming System — ACOG + RMR Type 2 — A 4x32mm ACOG and a 3.25 MOA LED red dot share a single quick-release Picatinny mount. Shift to the dot for close-range work or stay on the magnified reticle for distance holds — no control inputs required.
• Dual-Illuminated Green Crosshair 5.56 Reticle — Fiber optics drive illumination in ambient light; tritium takes over in low light. No batteries are needed for the ACOG reticle. BDC stadia are calibrated to 5.56/.223 ballistics for holdover references out to distance.
• No-Tool External Windage and Elevation Adjusters — Dial in corrections in the field without a coin or screwdriver, and the sealed design keeps the adjusters waterproof to 11 meters even without caps — no fumbling for tools when conditions change.
• Rugged Aluminum Alloy Housing with Cerakote FDE Finish — The hard-anodized aluminum body is finished in Cerakote Flat Dark Earth for corrosion resistance and reduced signature, and the overall construction is built to withstand the sustained recoil and impact abuse of hard field use.
• Quick-Release Picatinny Mount with Backup Iron Sights — The included TA51-style flat-top quick-release mount installs and removes without tools, and factory backup iron sights provide a proven fallback aiming solution if either optic is ever out of action.
• Multi-Coated 32mm Objective Lens — Multi-coated optics across the 32mm objective reduce glare and increase light transmission, maintaining a clear sight picture in bright sunlight and in low-light conditions near dusk.
