EOTECH HWS EXPS3 Series
Video | What’s Included | Specs | Pictures | Restrictions
The EXPS3 Series is the king of the castle when it comes to EOTECH optics. It features a QD lower 1/3rd mount, side-mounted buttons, and 10 dedicated night vision modes alongside the standard 20 daylight brightness settings. Since EOTECH uses technology different from your standard red dot optics, their lens coatings can allow for far more light transmission. This, paired with the large open window, makes EOTECH one of the best-performing optics under night vision.
