The black EOTech EXPS3 Holographic Weapon Sight
is built to perform under extreme conditions while enabling rapid
both-eyes-open sighting at close and medium range and conserving
valuable rail space. To get users precisely on-target, impact point
correction is made at 1/2 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 11.2 ounces, the
EXPS3 was designed for use on the M4 platform but will perform on an
array of bolt-action rifles and lauchers. It has an integrated quick
release Picatinny/Weaver Mount for fast and easy removal and
reinstallation without having to re-zero, is submersible to 33', and is
internally fog resistant. The sight runs on a single included CR123
battery with a continuous runtime of about 600 hours on a medium
setting, with 30 selectable intensity levels: 20 for use from dawn to
dusk and another 10 for use with night vision devices, when operating in
the dark.
