27 owner reviews, fewer than most models here
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-C-100552 runs at fixed 4x magnification with a 32 mm objective and a 7-degree field of view. The Crosshair reticle keeps targeting simple and recognizable. The Flattop mount designation suits standard M1913 rail-equipped platforms, which is the most common configuration in the market.
At 2.0 lb the scope is heavier than some ACOG variants, which may factor into setup decisions for weight-sensitive applications. The body material is listed as plastic, which is worth verifying against Trijicon's current product documentation at this price level.
The 4.7-star average from 27 reviews is strong for a scope at $1,812.03 and places this variant above several of its ACOG siblings in terms of buyer satisfaction. The sample size is moderate but meaningful at this price tier.
Pros
- 4.7-star rating is among the higher ACOG scores in this review group
- Flattop mount is compatible with the most common modern rail configurations
- 7-degree field of view at fixed 4x is practical for a compact optic
- Fixed magnification removes the mechanical complexity of a zoom ring
- 27 reviews provides a more credible sample than single-digit review counts
Cons
- Body listed as plastic, which is unusual for a scope priced above $1,800
- Fixed 4x has no magnification flexibility
- 2.0 lb weight is on the heavier side for a compact fixed-power optic
- No illumination source confirmed in available product data

What buyers say
At 4.7 stars from 27 reviewers, the TA31-C-100552 is one of the better-received ACOG variants in this segment. The score suggests buyers are largely satisfied with the optical performance and build quality for their intended use cases. The limited sample means caution is still warranted for a purchase above $1,800.

Frequently asked questions
What does the Flattop mount mean for compatibility?
A Flattop mount is designed for rifles with a flat top receiver and a MIL-SPEC 1913 Picatinny rail. This is the most common rail configuration on modern AR-platform and many other current production rifles. If your platform uses a Picatinny rail, this ACOG variant should mount directly without an adapter.
How does the TA31-C-100552 compare to the TA31-D-100553?
Both are fixed 4x ACOG optics with 32 mm objectives and Crosshair reticles, but they differ in mount and finish. The TA31-C-100552 uses a Flattop mount and standard black finish, while the TA31-D-100553 uses a Quick Release mount and an FDE finish with RMR Type 2 compatibility. The TA31-C-100552 also carries a higher buyer rating, 4.7 versus 4.2, from a larger review sample.
Is the plastic body a quality concern at this price?
The plastic body designation in the product data is worth verifying because Trijicon ACOG models are typically built from forged aluminum. It is possible that plastic refers to a specific sub-component such as a housing cap or lens cover rather than the primary tube. We recommend checking Trijicon's official product page or contacting hello@visionhut.com before purchase to confirm construction materials.
