My guess, and that's what it is, is that you would need a low mount for co-witness with that rail. The high mount definitely won't co-witness.

A low mount wouldn't be hard to come by though, right?
And even though the high mount wouldn't co-witness, it will still probably be better than mounting it directly on top of the A2 carry handle, right?
