Not anywhere near level - Knight's Armament Rail Mount Anti-Cant Devices

I'm wondering if all the four and five star reviewers are checking to see if this thing is level once installed, or if they are just slapping it on their firearm and calling it good. Mine is nowhere near level. I checked it with several leveling devices (to include one from Wheeler), and even moved it to several places on the rail to make sure it wasn't my receiver that was defective. I also flipped it around and tried it both ways. Even if I had not been using the other leveling devices to verify, I could see that my rifle was obviously canted when this device read level.

Mounting a level directly to the rail and under the scope out of the way is an awesome concept in my opinion, and much better than having it sticking out the side like the ones mounted to the scope. However, with no means of adjustment, the end user has no way to truly level the device if it is defective, as mine obviously is.

Unfortunately for me, I bought this thing a while back, and have only recently gotten around to trying to install it on my latest rifle build, so I am well past the window to return it. Otherwise, I would return it. I would NOT recommend this product to anyone else.
