Green Laser with Flashlight I mounted this laser on the bottom rail of a KSG shotgun for home defense. The green laser, by itself, is bright enough to illuminate any room search for an intruder. After a while, the momentary laser switch intermittently malfunctioned and I installed the supplied button switch in its place. The button switch works well. The flashlight is very good but requires frequent recharging. The rechargeable battery for the flashlight doesn't last long. And, you can't recharge the laser battery because it is too small for the charger. Mounted on the bottom rail, I was unable to adjust the laser to POI. I took the cover off and moved the laser mount to POI manually. That said, this laser and light work the best of any I have used (this includes the $1K Fraser/Volpe MARS) and, for my purposes, is deadly. IF the laser momentary switch, laser adjustments and charger were all without issues, this laser would easily get a 5 star rating. If your purpose is to defend your home, you cannot do better than this shotgun, laser and flashlight combination. I do not know the integrity of this setup for the field.
