I have a full metal bracket for my rear QS8. They are incredibly sturdy brackets and will easily hold up a M22. They also will have the ability to go about 3-4" from the wall. The only caveat about the FMB is that you have to drill the bracket into the speaker. This is not a problem, because Axiom tells you where to do it and it does not affect sound quality, but just be prepared to have to do it.
