LaserMax Guide Rod Laser meets or exceeds both Mil-Spec and Homeland Security durability test standards (drop tests/blowing sand/temperature and humidity extremes/salt water/fog/deep water immersion/20,000+ rounds live fire). It has an on/off switch on the takedown lever. No gunsmithing required to install. These pulsating red lasers install as the internal guide rod as close to the bore as possible for a close point of aim/point of impact relationship. Factory aligned for center-of-mass accuracy at 20 yards/they never need realignment/even after changing batteries. The ambidextrous on/off switch is located in the custom take-down lever for deliberate activation.
