Trijicon ACOG ECOS 4x32 FDE Green Crosshair .223/5.56 BDC Optic

The Trijicon ACOG ECOS 4x32 delivers battlefield-proven magnified optics with integrated close-quarters capability through its embedded red dot sight. This dual-optic system eliminates the need for separate CQB and distance optics on tactical rifles.

What Makes This Different

The ECOS (Enhanced Combat Optical Sight) combines a traditional 4x32 ACOG with a miniature reflex sight mounted at the 12 o'clock position. This configuration provides instant transition between 4x magnification for precision shots and 1x red dot acquisition for close-range engagements. The Flat Dark Earth finish matches modern tactical rifle systems while the tritium-illuminated reticle functions without batteries in all lighting conditions.

Key Features

• Dual-optic system with 4x32 ACOG and integrated reflex sight
• Green crosshair reticle with .223/5.56 bullet drop compensation
• Tritium and fiber optic illumination requires no batteries
• Flat Dark Earth anodized aluminum construction
• TA51 flattop mount fits standard Picatinny rails
• Waterproof to 11 meters and fog-resistant design
• Forged aluminum housing rated for .50 caliber recoil

Field performance centers on the rapid target acquisition capabilities across multiple engagement distances. The primary 4x optic handles precision shots from 100-600 meters while the top-mounted reflex sight enables immediate close-quarters response. Both reticles maintain zero independently and the tritium illumination provides consistent aiming references during low-light operations. The robust construction withstands repeated recoil cycles and environmental extremes.
