Works fairly well for odd position light mounting - FAB Defense 10 Position Adjustable Tactical Light Mount

Put this on a IDF clone X95, but overall it works fairly well. It can be finicky holding a flashlight, I found I needed to remove the rubber washer to get it to be tight enough, but if you tighten it too much, it will no longer pivot and will cant slightly. I was able to get a sweet spot where it securely holds the light, but can still pivot. One benefit is that you can quickly pivot to either side, or left or right handed use. Thumb screw for removing it is somewhat small, but is nice to remove it without tools if needed.
