Excellent light - SureFire X300V Flashlight

This is a top notch Surefire light. I bought it for its 150 lumen output, which is just right for CQB, and the potential of using its IR output, which I have not played with yet. Works great on a handgun. Works great on a carbine. I don't see any flaws. I read in a few reviews that the mount is very tight. This is true, the mount is tight. It's more of a small annoyance than a major flaw.
