SureFire's M313V Vampire Weaponlight is the perfect addition to a nighttime shooting setup. It features 2 modes; "normal" light and infrared light. The "normal" mode produces a powerful beam of 250 lumens, while the IR mode gives off 100 milliwatts of infrared light, completely invisible to those without night vision devices. Twisting the self-locking bezel-ring switches between modes instantly, and can be done without even looking. The M313V's can be mounted onto any platform using a MIL-STD 1913 Picatinny rail mount via an RM45 mount. This system will give the M313V an offset position to decrease the weapon's profile and reduce the chance of snagging. In addition, the M313V comes with a DS-SR07-D-IT dual remote switch. This easy-to-use system can simultaneously activate the M313V, as well as an ATPIAL or DBAL laser.
