Just the pics there is a machine mark on the mount where the screws go through. That's where it looks like its bent. When you disassemble it it lays as flat as could be
I recently installed one of these on my railed M4, with a MiniScout at the 10:30 position. It's nice to be able to hold the handguard without the light in the way. Also, the Thorntail puts the light much further out, reducing barrel shadow. Haven't shot with it yet, but so far I like how it handles.
The HSP Thorntail is just awesome. I mounted one on my SR-556. They make the entire setup streamlined and very clean.
