The EXPS3 is an excellent choice not only for hunters, but for professionals such as the U.S. Special Operations Command (USSOCOM), which has standardized on the HWS as its weapon optic for close quarter situations. The EXPS3 offers true two eyes open shooting for fast target acquisition, as well as a 7 mm raised base for iron sight access and night vision capability. It also has side buttons and an adjustable, locking, quick-detach lever for easy installment.

  • Single transverse 123 battery to reduce sight length.
  • Shortened base only requires at most 2 3/4 inch of rail space.
  • Battery cap and latch are eliminated and replaced with a simple O-ring, tethered cap; better sealing is achieved.
  • Battery compartment is now separated from the base to allow it to hover over the delta ring of the rifle.
  • Average battery life at brightness level 12 is roughly 500-600 hours.

Will the HWS hold zero as temperature changes?

EOTech's sights will experience a point of impact shift away from the point of aim when the sight is used at a temperature different from the temperature at which the sight was zeroed. This shift is greater the more extreme the temperature change. For example, when a sight is zeroed at 70°F then acclimated to 50°F, less shift will occur. On the other hand, if zeroed at 70°F, then acclimated to 0°F, more shift could occur. The maximum shift will occur at temperature extremes and could be up to 5 MOA. Therefore, to acheive optimum accuracy, the sight should be re-zeroed whenever the temperature changes markedly from the temperature at which the sight was zeroed.
