This Trijicon ACOG 4x32 Dual Illuminated Red Crosshair scope with a .223 Ballistic Reticle and TA51 Mount has been adapted from the battlefields with the improvement of a red dot sight on top for close encounters. The main scope offers a dual illuminated reticle through the use of fiber optics and tritium, while the ranging reticle provides bullet drop compensation out to 800 meters without manual adjustments.
