Trijicon ACOG 4x32mm Rifle Scope: Unrivaled Performance with Red Triangle Post Reticle

When evaluating optics for a serious shooting platform like the M16 or AR-15, few names resonate with the same authority and proven reliability as Trijicon. The Trijicon 100213 ACOG 4x32mm Riflescope with Illuminated Red Triangle Post Reticle stands as a testament to this legacy. Engineered for unwavering performance in the most demanding conditions, this fixed-power telescopic sight has become an icon, trusted by military, law enforcement, and discerning civilian shooters worldwide. It’s not just an optic; it’s a strategic advantage designed to enhance hit potential in any lighting scenario, offering a robust, battery-free solution to critical aiming challenges.

Why Choose the Trijicon ACOG 4x32mm with Red Triangle Post?

For operators and enthusiasts asking, "What is the best combat-proven optic for my M16 or AR-15?" or "How can I achieve rapid target acquisition and precision without relying on batteries?", the Trijicon ACOG (Advanced Combat Optical Gunsight) provides a compelling answer. This particular 4x32mm model is meticulously designed for close-to-medium range engagements, offering a versatile balance between wide field of view and sufficient magnification for accurate shot placement.

The core problem this ACOG solves is the need for a truly dependable aiming solution that performs flawlessly, regardless of environmental factors or power source availability. Unlike many modern optics that require batteries, the ACOG's Tritium-phosphor lamp illumination system offers a distinct, continuous glow, ensuring your reticle is always visible, day or night, for decades. This eliminates the catastrophic failure point of dead batteries in a critical situation, providing unmatched peace of mind.

Exceptional Design & Uncompromising Durability

The Trijicon ACOG is internally-adjustable and incredibly compact, making it an ideal choice for a variety of shooting applications. Every aspect of its mechanical and optical design has been meticulously chosen to deliver superior performance.

• Robust Construction: Crafted from a single piece of aerospace-grade aluminum, this ACOG model (UPC: 719307301252) boasts an incredibly rugged body that is nearly indestructible. The Black Hardcoat Anodized finish isn't just for aesthetics; it provides exceptional scratch and corrosion resistance, ensuring the scope can withstand the harshest environments imaginable, from desert dust to humid jungles.
• Battle-Tested Reliability: The ACOG's reputation for ruggedness is legendary. It has been subjected to and passed rigorous military testing, proving its ability to maintain zero and function reliably after extreme shocks, drops, and temperature fluctuations. This makes it an ideal choice for anyone who needs an optic that can truly take a beating and keep performing.
• Weatherproof Performance: Built to meet or exceed military specifications, the Trijicon ACOG is completely waterproof and fog-proof. Its nitrogen-filled housing prevents internal fogging due to temperature changes, ensuring a clear sight picture in rain, snow, or humid conditions.

The Power of the Red Triangle Post Reticle

The Illuminated Red Triangle Post Reticle is a standout feature of this ACOG. It combines the speed of a red dot sight with the precision of a magnified optic.

• Rapid Target Acquisition: The bold red triangle draws your eye instantly to the center, facilitating incredibly fast target acquisition in dynamic scenarios. For close-quarters combat (CQC) or rapid engagements, simply place the triangle over your target and fire.
• Precision Aiming: For more precise shots at extended ranges, the tip of the triangle can be used as an aiming point, offering a fine point of aim. This dual functionality is what makes the ACOG's reticle system so effective and versatile.
• Tritium Illumination: The reticle is illuminated by a Tritium-phosphor lamp, providing a bright, clear red glow without the need for batteries. This self-luminous reticle is designed to last for many years, offering consistent visibility in low-light conditions, dawn, dusk, or complete darkness. This passive illumination system is a critical advantage for continuous readiness.
• Bindon Aiming Concept (BAC): Trijicon's patented Bindon Aiming Concept (BAC) allows for "both-eyes-open" shooting. By utilizing the bright, illuminated reticle, the shooter can acquire targets quickly with both eyes open, maintaining full situational awareness while simultaneously focusing on the reticle for a magnified, precise shot. This revolutionary technique merges the benefits of a magnified optic with the speed of an unmagnified sight, a crucial advantage in fast-paced tactical situations.

Optimal Optical Performance

The clarity and brightness of the Trijicon ACOG's sight picture are immediately apparent, a result of Trijicon's commitment to superior optical engineering.

• Multi-Coated Lenses: The multi-coated lenses optimize light transmission across the entire visible spectrum, resulting in exceptional clarity, sharpness, and true-to-life color reproduction. This means brighter images in low light and crisp details even in challenging conditions.
• Generous Field of View: With a Field of View of 36.80 ft @ 100 yds, the ACOG provides ample peripheral vision, allowing shooters to maintain crucial situational awareness and track moving targets effectively.
• Comfortable Eye Relief: The 1.50" eye relief provides a comfortable and consistent sight picture, reducing eye strain and allowing for quick target reacquisition after recoil. The 32mm objective lens ensures efficient light gathering for a bright image.
• Fixed 4x Magnification: While some might debate fixed vs. variable magnification, the 4x fixed power offers several distinct advantages for a combat optic. It simplifies operation, reduces potential points of failure, and provides a clear, consistent sight picture without the need for constant adjustment. This fixed power is ideal for the common engagement distances of the M16 platform, bridging the gap between close-quarters and intermediate ranges.

Designed for the M16 Platform

This specific ACOG model (100213) is explicitly designed for the M16 family of rifles, featuring an integrated M16 Carry Handle Base mount. This direct attachment ensures a secure and stable connection, maintaining zero even under heavy use. For owners of classic M16s or AR-15s with carry handles, this ACOG provides a seamless, period-correct, and highly effective optical upgrade. The included carry handle screw and washer kit makes installation straightforward and robust.
