Electro-Optics are guaranteed forever. It's an unlimited lifetime guarantee.

Activated through motion sensing technology, MOTAC immediately powers up illumination when it senses motion and powers down when it does not in order to extend battery life.

Highly efficient, ultra-wide broadband, anti-reflection lens coatings reduce surface reflections to extremely low levels across the entire visible spectrum providing superior light transmission.

Deflection armor trapezoidal surfacing breaks up the shape and visibility of the optic along with slide serrations and grip checkering to add function to the form of electro-optics.
