Trijicon ACOG 4x32mm Illuminated Green Chevron .223/5.56 BDC Riflescope - FDE

The Trijicon ACOG (Advanced Combat Optical Gunsight) 4x32mm is a combat-proven, fixed-magnification riflescope purpose-built for .223 Remington / 5.56x45mm NATO carbines. The TA31-D-100313 configuration features an illuminated Green Chevron reticle with an integrated bullet drop compensator (BDC) calibrated for holdovers out to 800 meters; the chevron tip is designed to be zeroed at 100 meters for fast, intuitive aiming.

Reticle illumination is supplied by a combination of fiber optic daylight collection and tritium, providing a battery-free, always-on aiming point in any lighting condition. The multi-coated optics deliver a crisp sight picture through a generous 1.50" eye relief and a wide 36.80 ft @ 100 yds field of view, with adjustment clicks set at 2 per inch at 100 yards for precise BDC hold points across the calibrated range.

The optic is built around a rugged forged aluminum housing finished in a low-glare Flat Dark Earth (FDE), weighing just 14.90 oz with an overall length of 5.98". This listing includes the TA51 flattop mount for direct attachment to MIL-STD-1913 Picatinny rails. Manufactured in the USA to Trijicon's combat-tough standards, the ACOG has earned its reputation as one of the most reliable fixed-power combat optics available to military, law enforcement, and civilian shooters.
