The Trijicon ACOG 4x32 ECOS (Enhanced Combat Optical Sight) system is a dual-optic configuration combining a fixed magnification ACOG with a top-mounted RMR Type 2 red dot sight. Designed for rapid transition between magnified and non-magnified aiming, the ECOS system supports both close-quarters and mid-range engagements.

The ACOG utilizes a battery-free fiber optic and tritium illumination system, automatically adjusting brightness based on ambient light conditions. The integrated RMR Type 2 provides a compact, battery-powered red dot for close-range targeting.

These ECOS models feature a Cerakote Flat Dark Earth (FDE) finish and are configured with BDC reticles calibrated for .223/5.56, optimized for standard ball ammunition. The system is built on a forged aluminum housing for durability and includes the Bindon Aiming Concept (BAC) for rapid target acquisition.
