Description

Trijicon ACOG 4×32 Riflescope, Red .223 Chevron Reticle, TA51 Mount, Flat Dark Earth

The Trijicon ACOG TA31-D-100310 4×32 riflescope brings a red .223 chevron to a Flat Dark Earth housing. Its TA51 mount is included, and the scope uses battery-free fiber-optic and tritium illumination.

Red Chevron Reticle

Choose this FDE version when you want an earth-tone finish without changing the familiar red-chevron reticle. It offers the same fixed 4x format as the black TA31F, with a Cerakote exterior that complements a different color scheme.

An open chevron gives the sight picture a distinct pointed center without filling it with a solid triangle. The additional ballistic markings belong to this particular reticle, so the model designation matters as much as its color when comparing ACOGs.

Battery-Free Fiber Optics and Tritium

Fiber optics collect available light to illuminate the reticle during the day, while tritium provides illumination in low light. You do not need to switch the scope on or keep a spare battery for its reticle. Brightness responds to available light rather than a manual dial.

The reticle remains etched into the optical system, so its pattern is not created solely by illumination. This gives you a visible reference even when the illuminated portion is less prominent against the background. The scope itself has no battery compartment.

Compact Fixed-Power Construction

The scope combines fixed 4x magnification with a 32 mm objective lens. Its forged 7075-T6 aluminum housing is sealed and nitrogen-filled, protecting the multi-coated optics. It has a 7-degree field of view and an exit pupil of approximately 8 mm.

Included Mount and Fit

The included TA51-style thumbscrew mount attaches to a compatible flattop rail. The ACOG uses a dedicated mounting base rather than conventional riflescope rings. It has a relatively short eye relief of 1.5 inches, so check your available rail space and normal viewing position before choosing a mount.
