Trijicon TA31D ACOG 4x32 Dual Illuminated Red Chevron

Trijicon TA31D ACOG 4x32 Scope

The Trijicon ACOG remains the gold standard for combat optics, and this 4x32 configuration represents the perfect balance of magnification, field of view, and durability for modern rifle systems.

Illumination System

This scope employs a dual-illumination design combining fiber optics and tritium. The fiber optic element gathers ambient light during daylight hours, while the tritium provides a self-illuminated aiming point in low-light conditions. The result is a bright, reliable red chevron reticle that performs in virtually any lighting environment—no batteries required.

Reticle and Ballistics

The red chevron reticle is specifically calibrated for M193 ammunition (5.56mm, 55-grain full metal jacket) fired from a 16-inch barrel. The design is elegant in its simplicity:

• Zero point: Tip of the chevron at 100 meters
• Range capability: BDC extends to 800 meters
• Range estimation: The 5.5 MOA width of the chevron base equals 19 inches at 300 meters, allowing you to estimate range on silhouette targets

Build Quality

Constructed to military specifications, this scope is sealed, waterproof, and built to withstand the rigors of professional use. The matte black finish resists glare and blends seamlessly with modern rifle platforms.

Whether you're training, competing, or relying on your rifle for serious purposes, the ACOG delivers the optical clarity and reliability that has made it the choice of military and law enforcement professionals worldwide.
