The NCStar Flashlight and Green Laser with Rail Mount (AQPTFLG) uses a simple QD mount. This set up features two separate front bezel assemblies for different functions. One features a green laser diode and the other has a 1 Watt LED bulb that has a peak output of 35 Lumens. This is a nice, multi-use piece of equipment. Includes a laser and separate flashlight, and one CR123a battery.
