I know it's an ATI muzzle mount on a shotgun, and I know it's some simple light. But I'm having trouble finding any info on the light mount they show. The description they give at the ATI website is "1 inch Tac Mount" and they make no refrence to make or model. That description would suit LOTS of different mount, as such the search engines come up with nothing. If anyone can tell me what this thing is or who makes it id appreciate it, thanks.
