The Trijicon TA31 is a fixed 4x32 Advanced Combat Optical Gunsight (ACOG) featuring a red illuminated chevron reticle, designed for rapid target acquisition and ranging capability at intermediate distances. Illumination is powered by a combination of fiber optics for daylight conditions and tritium for low-light use, providing continuous reticle visibility without batteries.

This optic is outfitted with an AGA-ARD (Anti-Glint/Anti-Reflection Device) kill flash, reducing forward signature by minimizing lens reflection. Flip-up lens caps are installed for protection of the objective and ocular lenses when not in use. The optic body is constructed from forged aluminum for durability under adverse conditions and is nitrogen-filled for fog resistance.

Note: This unit is a few years old and the tritium has started to dim. The fiber remains bright and clean.
