Trijicon ACOG 4X32 Riflescope TA31-H

A combat tested prism optic with over 20 years of deployment.

The Trijicon ACOG (Advanced Combat Optical Gunsight) 4x32 TA31-H is a fixed magnification riflescope engineered for durability and performance in combat situations. This optic integrates a distinctive horseshoe .223/5.56 BDC reticle, balancing close-quarters speed with long-range precision in a compact design. With over two decades of combat experience and more than a million units produced, the ACOG has been extensively used by U.S. Special Operations Forces and Marines across various combat zones.

Key features of the ACOG 4X32 TA31-H include:

• Durable 7075-T6 aircraft aluminum housing
• Dual-illumination system using fiber optics and tritium
• Horseshoe .223/5.56 BDC reticle for target acquisition and ranging
• Both-eyes-open design using the Bindon Aiming Concept
• Waterproof up to 100 meters
• Fixed 4x magnification
• TA51 thumbscrew mount for Picatinny rails

The ACOG 4X32 TA31-H is available in black, gray, green, and Flat Dark Earth (FDE) colors, with a choice of green or red reticles to suit various preferences and operating environments.

At the heart of this optic is the horseshoe .223/5.56 BDC (Bullet Drop Compensator) reticle. This innovative design allows for rapid target acquisition at close range while providing holdover points for accurate shooting out to 800 meters. The reticle's effectiveness is enhanced by the ACOG's dual-illumination system, which uses fiber optics to adjust reticle brightness in daylight and tritium for low-light visibility. This passive system eliminates the need for batteries, ensuring the reticle remains visible in all lighting conditions without the risk of power failure.

The optic's legendary durability stems from its forged 7075-T6 aircraft aluminum housing. This robust construction, combined with the fixed 4x magnification that eliminates complex moving parts, contributes to the ACOG's reliability in challenging environments. Multi-coated lenses provide exceptional clarity and light transmission, delivering a clear sight picture across various conditions.

One of the ACOG's most innovative features is its compatibility with the Bindon Aiming Concept (BAC). This both-eyes-open shooting method potentially enhances situational awareness and target acquisition speed, crucial advantages in dynamic combat scenarios. The fixed 4x magnification offers a balance between target identification at range and close-quarters awareness, making it versatile across different engagement distances.

While initially designed for military applications, the ACOG 4X32 TA31-H has found favor among law enforcement officers, civilian sport shooters, and hunting enthusiasts who value its durability and consistent performance. Its design focuses on providing a reliable sighting system for users who require unwavering performance in demanding conditions

The Trijicon ACOG 4X32 TA31-H represents a culmination of combat optic design, informed by real-world usage and continuous refinement. Whether in the hands of a military professional or a civilian shooter demanding reliable performance, the ACOG delivers consistent results in challenging environments. Its combination of durability, innovative features, and combat-proven design make it a trusted choice for those who require a dependable optic in critical situations.
