I don't expect a scope mounted on any mount to remain level when moved between rifles. QD mounts or other wise.
I run ADM and the Larue C.A.N. SPR mount on my ARs primarily for the convenience of tool less removal. RTZ in my experience is acceptable for GP use when removing and re-attaching the optic to the same rifle. Moving from rifle to rifle with the those mounts mentioned, I have experienced POI changes as large as 6" @ 100 yards. Many times, significant adjustment to the QD lever tension is required when doing so, which probably explains the POI shift. I have come to appreciate the tool less design of adjusting QD lever tension on the Larue mount and of course the cost. Ditto on plumbing to an external leveling source, always.
