Oh so close..... - Viridian V300 Long Range Illuminators w/ Powered Remote Pad for Zoom - 370 Yards Range

The light itself is wonderful. I love the adjustable brightness and zoom. Works very well. However, the rail mount is horrendous. It is plastic and is not stable on the rail. It mounts to the light securely but does not have a tighten down adjustment for attaching to the rail, only a push button. When attached to the rail, there is so much play, it is laughable. Bottom line, the light is awesome, but prepare to buy an aftermarket rail mount.
