Illuminate the area quickly to ensure positive identification and rapid target acquisition. Bright, dependable, and truly ambidextrous, PL-3 Valkyrie provides an advantage in any tactical situation. Industry leading adjustable sliding block. This sliding block allows for more flexible positioning on the light on the rail, m aking it compatible with a wider range of short builds. Secure screw locking mechanism. Simply unlock the screw locking device by hand, with a hex wrench, or using a coin, and then push it and slide the locating block at the same time to position the light. When the installation is complete, the light will remain stably mounted shot after shot. We conducted an extreme reliability test on a random sample of 10 individual PL-3 Valkyrie. In the very high recoil (approximately 37 ft-lb or 50J) simulated shooting test, all 10 examples remained intact and fully functional after 45,000 continuous rounds.
