The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other optics: binoculars, telescopes, spotting scopes, rifle and hunting scopes, rangefinders, night vision and monoculars we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The Trijicon TA31-D-100549 operates at a fixed 4x magnification with a 32 mm objective lens. The field of view is 7 degrees, which is standard for this class of compact fixed-power optic. The Chevron reticle is a Trijicon-specific aiming reference that many users find intuitive for range estimation.
The body is listed as plastic, which differs from the aluminum or forged construction found on some other ACOG variants. It mounts on Picatinny rails and weighs 1.0 lb, keeping the overall package light for a premium optic. The black finish is conventional.
At $1,794.95, this scope sits in the upper range of the ACOG family. The 4.2-star average from 29 reviewers is reasonable but below some of its Trijicon stablemates, which may reflect buyer expectations at this price level.

The TA31-D-100549 holds a 4.2-star rating from 29 reviewers. That score is respectable but modest by Trijicon ACOG standards, where several models rate above 4.7. Buyers at this price tier tend to have high expectations, and the plastic body construction may factor into the somewhat restrained enthusiasm.

Frequently asked questions
What is the Chevron reticle and how is it used?
The Chevron reticle is a downward-pointing V-shape used as the primary aiming point. In Trijicon ACOG designs, the tip of the chevron is the point of aim, and the width of the chevron at various heights can be used to estimate target range based on known target sizes. It is a practical reticle for quick target acquisition at moderate distances.
Is the TA31-D-100549 illuminated?
No illumination source is specified in the available product data for this model. Many Trijicon ACOG models use fiber optics and tritium for illumination, but whether this specific variant includes those features cannot be confirmed from the data on hand. Check Trijicon's current product sheet or contact hello@visionhut.com for clarification.
Why is the body listed as plastic on a $1,794 scope?
The body material is listed as plastic in the product data, which is unusual for a scope at this price tier. Trijicon ACOG bodies are typically forged aluminum. The plastic listing may reflect a specific sub-component or a data entry issue rather than the full body construction. Verify with the retailer or Trijicon directly before purchasing.
