8 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-D-100553 uses fixed 4x magnification with a 32 mm objective lens and offers a field of view of 36.8 feet. The Crosshair reticle is straightforward and familiar to most optics users. The Quick Release mount is a practical feature for those who swap optics between platforms regularly.
The FDE finish with RMR Type 2 designation means this variant includes accommodation for a miniature red dot sight on top, which expands close-range engagement capability. The metal body construction suits the $1,739 price point better than plastic-body variants in the same family.
With only 8 reviews at a 4.2-star rating, there is very little buyer data to draw from. The scope carries the Trijicon name and the Quick Release plus RMR combo are genuine differentiators, but prospective buyers should weigh the thin review record carefully.
Pros
- Quick Release mount simplifies swapping between platforms
- FDE with RMR Type 2 top cap adds a miniature red dot mounting option
- 36.8 feet field of view at 4x is standard for compact fixed-power use
- Metal body construction is appropriate for the price tier
- Fixed 4x is simple, robust, and requires no power adjustments
Cons
- Only 8 reviews provides very limited buyer feedback
- 4.2-star average is modest relative to other Trijicon ACOG models
- Fixed 4x offers no flexibility for varying distances
- $1,739 price demands confidence in optical quality that limited reviews make harder to assess

What buyers say
At 4.2 stars from just 8 reviewers, the TA31-D-100553 has the smallest buyer sample in this review group. The score is average for a Trijicon product. The thin review count means the rating could shift significantly with more purchases, so it is worth tracking for additional feedback before buying.

Frequently asked questions
What does the RMR Type 2 designation mean on this scope?
RMR stands for Ruggedized Miniature Reflex, which is Trijicon's miniature red dot sight line. The Type 2 designation refers to a specific generation of the RMR. The TA31-D-100553 includes a top cap or housing compatible with the RMR Type 2, allowing a miniature red dot to be co-witnessed on top of the ACOG for close-range use. Whether the RMR sight itself is included in the purchase price should be verified with the retailer.
How does the Quick Release mount work?
A Quick Release mount allows the scope to be attached and detached from a Picatinny or compatible rail without tools, using a lever or cam mechanism. This is useful if you need to move the optic between platforms or remove it for storage. Zero retention after re-mounting depends on mount quality, and confirming zero after any reinstallation is good practice.
Is the TA31-D-100553 illuminated?
No illumination source is specified in the available product data for this model. The color field references FDE with RMR Type 2, which describes finish and mounting, not illumination. Many Trijicon ACOGs use tritium and fiber optics for illumination, but this cannot be confirmed for this specific model from the available data.
