The Extreme-EXPS delivers true both-eyes open shooting, with a transversely mounted size-123 battery. It takes up only 2.4 inches of rail space, and features easy-to-adjust side buttons, and a quick-release throw lever for trouble-free attachment and removal without losing zero. The system is ambidextrous so the mount can release on either side of the gun.
EOTech repositioned the sight’s brightness and night-vision buttons to allow operators more room for magnifiers, rear iron sights or night-vision units. The Extreme-EXPS measures 3.5 by 2.4 by 2.8 inches, weighs 11.2 ounces, and is waterproof to 33 feet. It also features 20 brightness-adjustment settings, with several reticle options. l-3com.com/eotech.
