EOTech holographic sights are designed to be used with both eyes open so you can retain situational awareness and acquire a target faster than other optics which makes them great for hunting, close range competition shooting or combat. The EOTech is easily mounted to a Weaver/Picatinny rail.
The EOTech EXPS3 was chosen by the U.S. Special Operations Command (USSOCOM) as their primary optic for close-quarter battle. The EXPS3 features easy-to-adjust side buttons, 7 mm raised base and an adjustable, locking, quick-detach lever for easy attachment and removal.
This EXPS3-4 has 4 dots which are calibrated for M855 62gr FMJ ammo at approx 2,680 FPS on a 14.5" barrel. The four aiming dots will line up for different ranges from 50-600 yards.
