Trijicon offers the ACOG 5.5x50 -- the larger, more powerful version of the full-sized Trijicon ACOG -- designed for extended range shooting where additional magnification is required. This rugged, dependable aiming system is available with reticles calibrated to the trajectory of the .223 and .308 cartridges and provides precision aiming for targets out to 800 meters. To make the ACOG 5.5x50 even more effective, the ballistic correction in the reticle eliminates the need for external bullet drop compensation. It is entirely battery free, featuring a red chevron aiming point powered by Trijicon's fiber optics and tritium-based technology.
