The 2015 edition of EOTech's Model EXPS2 Holographic Weapon Sight is built to conserve valuable rail space while enabling rapid both-eyes-open sighting and tracking in a variety of conditions. This model's reticle features a 68 MOA outer ring with a 1 MOA center aiming dot for use in close to medium range encounters with a second aiming dot under the first to use at longer ranges with magnifiers. To get users on target faster, impact point correction is made at 0.5 MOA per click with a total windage and elevation adjustment range of 40 MOA to compensate for most terrain and conditions. Measuring just 3.8" and weighing a mere 11.2oz the EXPS2 has an integrated quick-release Picatinny/Weaver rail mount for fast and easy removal and reinstallation without having to re-zero, is submersible to 33', and is internally fog-resistant. It runs on a single CR123 battery with a continuous runtime of about 600 hours at a medium setting, with 20 selectable intensity levels for use in most lighting conditions.
