INSTALLATION
Installation was a simple task. The laser housing unscrews into two halves (right and left). The two halves are snapped together on the trigger guard and tightened. From there you simply need to zero the laser. I did this initially by aiming across the basement at a light switch and placing the dot atop the from sight. This is how I have rough zeroed red dots on AR15s for some time.

FIRST IMPRESSIONS
After getting the laser installed it was time to do some dry fire and get a feel for how it worked. The unit features ambidextrous operation with on/off/mode switches on both sides. One of the unique features Viridian uses is simply called "Instant On." This feature combined with the supplied ECR holster or by using their upgrade kit stuck to your holster makes the worry about operating switches and buttons under stress moot. The system is actually quite simple; a magnet in/on the holster activates an internal switch, turning the laser on and off when holstered or unholstered.
