Description

Trijicon ACOG TA31-CH 4×32 Riflescope, Red .223 Crosshair Reticle, TA51 Mount, Black

The Trijicon ACOG TA31-CH 4×32 riflescope combines a red crosshair reticle with fiber-optic and tritium illumination. The black .223/5.56 scope includes a TA51 flattop mount for a straightforward fixed-power setup.

Red Crosshair Reticle

This version is a natural choice if you prefer a conventional crosshair to the ACOG’s better-known chevron. Unlike the tritium-only TA01NSN, the TA31-CH uses a fiber-optic collector as well as tritium to illuminate its reticle.

The crosshair uses intersecting lines for a familiar central reference, with ballistic markings incorporated into the pattern. It is a different visual style from the ACOG chevron or horseshoe, making it a good fit when you prefer a conventional scope reticle.

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.
