The EOTECH® Model 558™ Holographic Weapon Sight has 20 daylight reticle brightness settings, and an additional 10 settings on night vision mode when using Gen I-III night vision devices. This is the preferred choice when long run-times are required on tactical rifles and shotguns. The Model 558 Holographic Sight operates on standard AA batteries, easily found all over the world. 2 Lithium 1.5V AA batteries provide 1,000 continuous hours at a nominal 12 setting, and 2 AA alkaline batteries provide 600 continuous hours at the same setting. Using the Model 558 Holographic Sight gives shooters maximum situational awareness when shooting heads-up with both eyes open by maximizing peripheral vision and eliminating blind spots. Button operation on the side rather than the front of the unit makes it fast and convenient for the shooter, and reduces rail space to use the 558 with EOTECH switch-to-side magnifiers. The Model 558 tactical sight mounts on any 1" Weaver® mount or MIL-STD-1913 Picatinny rail. A locking, quick-detach lever allows instant removal the sight from the rail and when re-attached the weapon will return to within 1 MOA. A submersible rating of 33 ft. (10 m) depth keeps your sight functioning in harsh, wet environments. The EOTECH Model 558 Holographic Weapon Sight is a rugged, high-grade tactical sight that provides rapid target acquisition and tremendous control over a wide engagement zone.
