When long run-times are required, the EOTech 556 is the sight to have. The Model 556 operates on the same CR123 lithium batteries manufacturers commonly use in law enforcement and military gear. The extended battery life and run-time of the 556, make it ideal when battery replacement is an issue. Used with an EOTech magnifier, this optic is mission-ready and perfect for mid to long-range shooting applications. It offers both speed and all-purpose versatility. The 556 holographic weapon sight is also night vision-compatible.
