hahaha, junior? Doesn't know what he's talking about? Lt.Col. Lutz, USMC (retired), presently of Knights Armament, is one of the most knowledgeable people here, he and 3rdtk take time out of their busy schedule to interact with us, but I'm sure you already know that. You may call me Junior and say I don't know what I'm talking about, that might have some truth.
Though for a change I don't fully agree with coldblue said about 3rdtk this time, as I think ARMS throw lever mount is one of the most brilliantly engineered yet simple mounts, I don't think anyone (KAC included) has come up with a QD mount as easy to use. Thumb nuts, wing nuts, as good as they are it's still faster and easier to use the throw levers.
Also, though myself lacking real field experience, what 3rdtk said about external adjustments has been validated by many real world, battlefield experiences.
What optics do you know of that's a modern design that still uses scope mount adjusted windage and elevation? ELCAN is one of them, and now Aimpoint too, it's a step backward IMHO.
