This is another possible option instead of the Snap Brackets [Link: av-express.com]

I have not used the Snap yet. I have used the Leon Tonecase and this seems like the same piece included in their kit. Depending on the TV, an inch could make a difference. I was using the Leon with the Chief Articulating Mount, like Sbsmarthomes with a 4K Samsung.

When I initially put the uprights on first then the mounting bracket, the TV sat too far off the wall. With a 4K TV the bottom is much deeper then the top half so that already makes the TV seem like its hanging far enough off the wall, especially when you can see the side of the TV in parts of the room.  I then tried reversing it but that caused issues with getting the mount retracted as well as blocking access to inputs for ethernet and HDMI.  In this case I ended up getting the side speaker adapter from Chief and then mounting the speaker bar uprights to that piece.
