The SureFire M612U 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 M612U also has a system disable feature, which completely disables the light for safe storage and transportation. The M612U is attached to the weapon with an RM45 mount that places the light in an offset position to lower the risk of snagging and reducing the overall profile.
