The SureFire M622U offers powerful illumination in a lightweight and compact package. The durable LED emitter is capable of withstanding heavy recoil and produces a 1000 lumen beam with an illumination distance of 213 meters. The beam is powerful enough to temporarily impair your target's vision, and has ample peripheral light for constant situational awareness. The light is instantly activated with a DS07 switch assembly which activates the light for as long as the switch is held down. The M622U also has a system disable feature, which completely disables the light for safe storage and transportation. The M622U is attached to the weapon with an American Defense Manufacturing throw leaver mount for quickly attaching/detaching the light from the weapon.
