Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red Review

What Makes Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red Stand Out?

The Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red is not just another optic; it’s a rugged, battle-proven piece of equipment designed for serious shooters. Manufactured by Trijicon, a company renowned for its durability and innovation, this ACOG (Advanced Combat Optical Gunsight) is built to withstand harsh conditions and deliver exceptional performance. The standout features are its fixed 5.5x magnification, a large 50mm objective lens for superior light gathering, and the iconic red chevron reticle, all without the need for batteries.

I’ve been using magnified optics for over a decade, and lately, I’ve found myself frustrated with scopes that require constant battery changes or those that fog up at the worst possible moment. I needed a reliable optic that could handle the rigors of both hunting and tactical scenarios, something I could trust my life to. This search led me to the Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red.

Upon unboxing the Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red, I was immediately struck by its robust construction. The forged 7075-T6 aircraft aluminum alloy housing feels incredibly solid, reassuring me of its ability to handle significant abuse. The weight is noticeable, but it gives a sense of substantial quality and purpose.

I considered the Leupold Mark 4 MR/T and the EOTech Vudu, both excellent optics, but the ACOG’s battery-free operation and reputation for extreme durability ultimately swayed my decision. The Leupold offered variable magnification but lacked the ACOG’s bombproof reputation. The EOTech Vudu, while offering a wider field of view, relied on batteries, which was a deal-breaker for my specific needs.

My first impression was one of excitement mixed with a little apprehension. I was excited to get it mounted and zeroed, but also aware that ACOGs can take some getting used to due to their fixed magnification and unique eye relief. Overall, however, I felt like I had a true top-tier optic in my hands.

Real-World Testing: Putting Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red to the Test

First Use Experience

My initial test of the Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red took place at my local range, primarily focusing on zeroing and familiarization with the reticle. I was mounting it on my AR-10 chambered in .308 Winchester. The range offered distances from 25 to 300 yards, allowing me to get a feel for the ballistic drop compensation (BDC) of the reticle.

The weather was slightly overcast with a light drizzle, but the ACOG performed admirably. The large 50mm objective lens gathered plenty of light, providing a clear and bright image even in less-than-ideal conditions. The red chevron reticle was easy to acquire quickly, drawing the eye naturally.

There was a slight learning curve involved, primarily getting used to the eye relief and the Binding Aiming Concept (BAC). The BAC allows for both-eyes-open shooting, which takes some practice but dramatically increases situational awareness. The only real issue I encountered was remembering to adjust my cheek weld to achieve proper eye relief at different distances.

Extended Use & Reliability

After several months of use, the Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red has proven to be incredibly reliable and durable. I’ve taken it on several hunting trips in varying conditions, from the dry heat of the desert to the cold, damp forests of the Pacific Northwest. It has consistently performed flawlessly.

The ACOG has shown no signs of wear and tear, despite being subjected to bumps, scrapes, and exposure to the elements. The finish is remarkably durable, and the internal components remain unaffected by temperature changes or moisture. Cleaning is simple; a quick wipe down with a lens cloth is usually all that’s needed.

Compared to other optics I’ve used, the Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red is in a league of its own in terms of ruggedness and reliability. Its battery-free operation is a huge advantage, and the clarity of the glass is exceptional. It outperforms any other optic I’ve used in scenarios where durability and immediate target acquisition are critical.

The red chevron reticle facilitates rapid target acquisition and provides accurate ballistic drop compensation for .308 Winchester rounds, making it a versatile tool for both hunting and tactical applications.

Performance & Functionality

The Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red excels at its primary function: providing a clear, accurate, and reliable aiming point in any lighting conditions. The Binding Aiming Concept (BAC) allows for both-eyes-open shooting, dramatically increasing situational awareness and target acquisition speed. The fixed magnification is a deliberate design choice that enhances the scope’s ruggedness and eliminates the potential failure points associated with variable magnification optics.

The scope’s strengths lie in its simplicity, durability, and exceptional glass quality. The red chevron reticle is easy to acquire and use, even under stress, and the BDC provides accurate holdover points for extended-range shots. The only potential weakness is the fixed magnification, which may not be ideal for extremely close-quarters engagements or situations where a wider field of view is desired. Overall, the Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red meets and exceeds expectations for a combat-proven optic.

Design & Ergonomics

The Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red features a robust and functional design. The forged 7075-T6 aircraft aluminum alloy housing is incredibly durable, while the overall weight is manageable. The scope is designed to be mounted on a flattop AR-style rifle, and the included adapter ensures a secure and stable platform.

The scope is user-friendly, but there is a slight learning curve associated with mastering the Binding Aiming Concept (BAC). The eye relief is somewhat critical, requiring a consistent cheek weld to maintain a clear sight picture. However, once mastered, the ACOG becomes an incredibly intuitive and effective aiming solution.

Durability & Maintenance

The Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red is built to last a lifetime. Its rugged construction and battery-free operation make it incredibly reliable in harsh environments. The tritium phosphor lamp is guaranteed to illuminate the reticle for up to 15 years, ensuring consistent performance without the need for batteries.

Maintenance is minimal; a quick wipe down with a lens cloth is usually all that’s needed. The scope is designed to withstand extreme temperatures, humidity, and shock, making it a true “set it and forget it” optic.

Accessories and Customization Options

The Trijicon TA55A ACOG 5.5×50 Rifle Scope, Red comes with a flat top adapter, allowing it to be directly mounted to any standard Picatinny rail. While the ACOG is largely self-contained, there are some accessories that can enhance its functionality.

• KillFlash Anti-Reflection Device: Reduces glare and prevents the optic from being easily spotted.
• LensPen: Provides a convenient and effective way to clean the lenses.
• Various Mounts: Offering different heights and offsets to optimize eye relief and cheek weld.

The ACOG is compatible with a wide range of aftermarket mounts, allowing users to customize the optic’s position on their rifle to suit their individual needs and preferences. Trijicon also offers various other reticle options, although swapping reticles requires professional gunsmithing.
