Overview
['The TA31-D-100367 uses a 4x fixed magnification with a 32mm objective lens and delivers a field of view of 36.8 feet. The Horseshoe Dot reticle is a Trijicon-specific design that combines a surrounding horseshoe with a central dot aiming point, giving fast close-range target acquisition without sacrificing precision.', 'The scope body is polymer construction with a Flat Dark Earth finish and a Picatinny mount included. At 2.0 lb it is not ultralight, but the weight is in line with similar 4x optics at this class. The FDE color option makes it a natural fit for certain platform setups.', "Twenty-one reviewers gave this scope a perfect 5.0, which is a meaningful sample for this price tier. The consistent praise reflects Trijicon's well-established quality control and the practical utility of the fixed 4x format with illuminated reticle."]
Pros
- Perfect 5.0 rating from 21 reviewers, a credible sample at this price
- 36.8-foot field of view at 4x is generous for a fixed-power optic
- Horseshoe Dot reticle suits both close-range and moderate-distance use
- Flat Dark Earth finish with Picatinny mount included
- Trijicon's fiber optic and tritium illumination needs no batteries
Cons
- Fixed 4x means no flexibility for close-in or long-range adjustment
- Polymer body at $1,299 may give some buyers pause versus aluminum-body competitors
- 2.0 lb weight adds up in a full-kit setup

Performance notes
At 4x magnification with a 32mm objective lens, this scope is built for consistent mid-range clarity rather than extreme zoom flexibility. The 36.8-foot field of view is wide for a 4x fixed, making target acquisition at closer ranges straightforward. The Horseshoe Dot reticle does not require batteries since Trijicon uses fiber optics for daytime illumination and tritium for low-light conditions.
What buyers say
All 21 reviewers gave it 5 stars, which is an unusually clean record for a product with enough reviews to matter. Buyers at this price point tend to be deliberate purchasers, and the satisfaction rate here reflects that the scope performs as expected for its intended use.

Frequently asked questions
Does the Horseshoe Dot reticle require batteries?
No. Trijicon's TA31 series uses a combination of fiber optics for daytime illumination and tritium for low-light use. This means the reticle stays lit without any battery dependency, which is a practical advantage for extended field use.
Is the polymer body a durability concern at this price?
Trijicon engineers their polymer-bodied scopes to strict tolerances, and the TA31 line has a long history of reliable use in demanding conditions. That said, buyers who prefer all-metal construction at the $1,299 price point should note the body material before purchasing.
What mount does this scope include?
The TA31-D-100367 ships with a Picatinny mount. Buyers should confirm compatibility with their platform's rail system before ordering. Questions can be directed to [email protected].
