Trijicon 3.5x35 ACOG Red Chevron M193 100291

The Trijicon ACOG 3.5x35 TA11-D-100291 in nickel boron finish with red chevron reticle calibrated for M193 ammunition is the purpose-built ACOG configuration for shooters running 5.56 55-grain FMJ ammunition from a 16-inch barrel - a reticle specifically calibrated for the most widely used military surplus and training ammunition configuration rather than a generic 5.56 reticle that requires mental adjustment for the specific load being run.

The Trijicon ACOG Scope TA11-D-100291 chevron reticle is zeroed using the tip at 100 meters with BDC holdover references extending out to 800 meters - the practical engagement range that the 3.5x35 ACOG covers effectively with M193 ammunition from a 16-inch barrel. The chevron tip provides the precise aiming point that accurate long-range holdover shooting demands, while the chevron's 5.5 MOA base width serves as a practical range-estimation reference — representing 19 inches at 300 meters, allowing the shooter to quickly estimate range using standard silhouette target dimensions.

The ACOG 3.5x35 TA11-D-100291 dual illumination system uses fiber optics to automatically adjust the red chevron brightness to available daylight conditions and tritium to maintain reticle illumination in complete darkness - the battery-free, always-on illumination system that the Trijicon ACOG platform is built around for reliable performance in any lighting condition, without requiring battery management.

The TA11-D-100291 nickel boron finish provides enhanced corrosion resistance and a distinctive appearance that sets this configuration apart from standard black anodized ACOG finishes. The included TA51 mount provides correct platform mounting.
