Description

Trijicon ACOG 4×32 Features and Performance

The Trijicon ACOG 4×32 BAC Riflescope with Green Chevron Reticle is built for shooters who want a proven fixed-power combat optic with fast target acquisition, rugged durability, and battery-free illumination. This TA31F-G configuration uses a green chevron reticle calibrated for .223/5.56, making it a strong fit for AR-platform rifles and other flattop carbines set up for general-purpose use.

Its fixed 4x magnification and 32 mm objective help provide a clear, capable sight picture for practical rifle shooting, while the green chevron BAC reticle supports both rapid engagement and more deliberate shot placement. Dual illumination from fiber optics and tritium helps keep the reticle visible in changing light without relying on batteries, which remains one of the defining advantages of the ACOG platform.

Built from forged 7075-T6 aluminum, this optic is designed for hard use in demanding conditions. The compact housing helps keep weight manageable while still delivering the durability and field-ready performance Trijicon optics are known for. The included TA51 flattop mount also makes this a practical ready-to-install setup for compatible rifle platforms.

With 1.5 inches of eye relief, a 36.8-foot field of view at 100 yards, and a .223/5.56 BDC reticle, this model remains a popular choice for shooters who want a durable magnified optic that does not depend on batteries. The Trijicon ACOG 4×32 is a strong option for training, defensive rifle setups, and general-purpose carbine use.
