Never disappointed - Viridian Weapon Technologies X5L-RS Gen 3 LED Universal Green Laser Sight w/Weapon Light

To start off, i have the pistol version of this, and well, it has been fantastic. So i got the rifle version, and it didn't disappoint either. The removable battery without having to remove the laser/light is one of my favorite parts. I kind of wished that they had come a second mounting bolt, but thats really my only complaint. The light isn't too bright for tight spaces but is not underpowered for open areas. Lights up out to 100 yards pretty well. As to the laser, it keeps on point even after banging around or 500 rounds. Onto the battery life, I have left both laser and the light on for an hour and was still going. But i would recommend using the coupon that you get to buy a spare battery.
