Yep, I got one and prefer using the green light. I got the red and used that too, and the white one.
I can light up beyond 300 yds.... I never had a battery go down on me on a night hunt...yet.... I use it on either of my rifles and got a little sticky pad on all of them, for the pressure pad switch. I even got a rail mount for the DPMS LR 308, or I can use the mount that comes with the light for any of my scopes.... I love it!
