This Green Spartan™ Laser features the latest LaserMax mounting technology and installs in the preferred rail location for each operator's personal comfort and ease of use. Once anchored, Spartan maintains precision accuracy over extensive live fire. Spartan emits the industry's brightest green laser aiming point and features a preservation mode that automatically deactivates the laser after a ten-minute period of inactivity, safeguarding against unintentional battery drain.

Over-sized electronic touch pads ensure effortless activation. The laser operates at a wavelength of 520 NM and its power output of less than 5MW provides a one-hour battery life.
