Trijicon ACOG TA31H-68 | 4×32 | Red Horseshoe/Dot | 100220

The Trijicon ACOG TA31H-68 is a fixed-power 4×32 optic with an illuminated red horseshoe and center dot reticle calibrated for 6.8 SPC ammunition. It uses fiber optics for daylight illumination and tritium for low-light visibility, and is designed for mounting on flattop-style rifles using the included TA51 adapter. This ACOG balances precise downrange aiming with rapid target acquisition in daylight and reduced-light conditions. Typical applications include carbine target shooting and field hunting where a calibrated, rugged optic is preferred.
