The Holosun LS321 provides users with a visible aiming laser, an IR laser and an IR illuminator for enhanced flexibility in a wide range of circumstances, giving users the ability to meet mission needs.
The unit is enclosed in an aluminum housing and is operated using a remote cable switch and mode selector. Windage and elevation adjustments zero all the lasers at once, and a focus-adjustment knob is also provided for the illuminator. The LS321 is powered by a CR123 battery.
