Trijicon TA55 ACOG 5.5×50 Rifle Scopes Advanced Combat Optical Gunsight Review

Let’s Dive into Trijicon TA55 ACOG 5.5×50 Rifle Scopes Advanced Combat Optical Gunsight

The Trijicon TA55 ACOG 5.5×50 Rifle Scopes Advanced Combat Optical Gunsight is more than just an optic; it’s a legacy of ruggedness and precision, forged in the crucible of real-world combat. Trijicon has a long-standing reputation for producing battle-proven optics, and the TA55 is no exception. With its fixed 5.5x magnification, massive 50mm objective lens, and iconic chevron reticle, this ACOG promises enhanced target identification and extended-range capabilities.

I’ve spent years relying on various optics, from red dots for close-quarters to variable-powered scopes for longer distances. However, I needed a dedicated optic for my DMR build, something that could bridge the gap between CQB and precision shooting, offering both rapid target acquisition and reliable accuracy at extended ranges. I wanted something battle-ready and dependable.

The Trijicon TA55 ACOG arrived in a sturdy polymer hard case, exuding quality from the moment I opened it. The ACOG itself felt incredibly solid, with a weight that speaks to its robust construction, and the finish was flawless. The included Trijicon TA51 flattop adapter looked equally well-made.

Compared to my experience with smaller 4×32 ACOGs, the TA55 seemed like a different beast altogether, offering a significantly wider field of view and brighter image. I also considered variable optics, but the ACOG‘s inherent simplicity and durability won me over. It felt like a tool, not a gadget.

My initial impression was one of excitement mixed with slight apprehension. The size was definitely noticeable, but the clarity of the glass and the promise of superior long-range performance made it worthwhile. I was eager to see if it would live up to the Trijicon name.

Real-World Testing: Putting Trijicon TA55 ACOG 5.5×50 Rifle Scopes Advanced Combat Optical Gunsight to the Test

First Use Experience

I first tested the Trijicon TA55 ACOG at my local shooting range, a mix of indoor and outdoor bays reaching out to 300 yards. The weather was overcast, typical of the Pacific Northwest, but visibility was decent. I zeroed the ACOG at 100 yards, and the adjustments were precise and repeatable, with clear clicks.

The large objective lens pulled in a surprising amount of light, making the target appear brighter than with my naked eye, even in the dim conditions. The chevron reticle was easy to pick up, and the Bindon Aiming Concept (BAC) worked as advertised, allowing me to keep both eyes open for improved situational awareness. Close range shots were surprisingly fast.

There were no immediate issues, but the eye relief was noticeably shorter than what I was used to, requiring me to adjust my cheek weld slightly. The clarity of the glass, however, was a revelation.

Extended Use & Reliability

After several months of regular use, the Trijicon TA55 ACOG has proven itself to be a reliable and robust optic. I’ve taken it through several training courses in varying weather conditions, from scorching summer days to rain-soaked autumn afternoons. It has performed flawlessly.

The Forged Aluminum housing has held up remarkably well, showing no signs of wear and tear despite being bumped and jostled around. Cleaning is simple, a quick wipe-down with a lens cloth is usually all it takes. The Trijicon lens pen does a great job for stubborn smudges.

Compared to my previous optics, the TA55 ACOG offers a significant improvement in target identification and long-range accuracy. The fixed 5.5x magnification is ideal for engaging targets out to 400 yards, and the illuminated reticle makes it easy to acquire targets in low-light conditions. Its durability is in a different league.

Performance & Functionality

The Trijicon TA55 ACOG 5.5×50 Rifle Scopes Advanced Combat Optical Gunsight performs exceptionally well in its intended role. Its accuracy is superb, allowing for consistent hits on targets at extended ranges. The clarity of the glass and the bright, illuminated reticle make it easy to acquire targets quickly and accurately in various lighting conditions.
