Trijicon is proud to offer the new Trijicon ACOG 4x32 Enhanced Combat Optical Sight (ECOS). This new model was designed for Special Operations forces of the US military, but is available for civilian and law enforcement applications. The Trijicon ACOG ECOS is the ultimate sight for both Close Quarter Battle (CQB) situations and longer distance shooting where accuracy and pinpoint bullet placement are required.

This rugged, dependable aiming system is available with a Bullet Drop Compensated (BDC) reticle calibrated to the trajectory of the .223 cartridge and provides precision aiming for targets out to 1,000 meters.

Two models of the Trijicon ACOG ECOS are available: The TA31 ECOS uses Trijicon’s patented fiber optics and tritium-based technology with a reticle that glows red continually in bright light, low light or no light at all. The TA01 ECOS model features Trijicon’s advanced tritium technology only — and both models feature back-up iron sights as specified by the U.S. Special Operation Command.

This innovative sighting system, weighing in at less than 16 ounces, including the mount, is designed for the M-16 series of rifles. A forged, 7075-T6 aluminum alloy housing gives the ACOG durability beyond the call of duty, and multi-coated lenses provide maximum optical performance in any light. The ACOG is also waterproof (Tested to 328 Ft / 100 Meters — five times the military’s required depth) and nitrogen filled to eliminate fogging, the Trijicon ACOG ECOS is made with pride in the USA at Trijicon’s ISO-approved Wixom, Michigan manufacturing facility.

The TA31ECOS Brown color. It has a Dual Illumination Red Crosshair .223 Ballistic Reticle. It comes with a mounted RMR Sight, Backup Iron Sights, an A.R.M.S.® Throw-lever mount and a Dust Cover.
