Absolutly awesome! - American Defense Manufacturing Holosun 509T QD Mount Titanium Lever

This is exactly what I was looking for my 509T's! I actually have three of the optics, of which one of them is on a ADM-mount. ...I realized I like the mount so much, that I'm gonna get a second one, for my third 509T. I'm personally looking to be as "done as possible" with locking an optic onto 1 firearm. Yes, the optic will need to be re-centered, but that's a given. I prefer to be "tool-less" going further, & these QD mounts do the job!

Easily recommended! Build quality, is great too.
