I am thinking of running an Eotech and a 1-6 with QD mounts on the same AR. Can I expect to maintain a zero when I swap out optics?

I'm not sure you can expect to retain zero even if you never remove the eotech.  With the 1-6x, it shouldn't be an issue if you use a quality mount.

Touche.
But yes, you can run 2 optics if you get 2 high quality QD mounts.

I run a QD red dot in AMD mount and  QD scope in Larue mount, both swapped regularly on tbe same rifle.  Return to zero is excellent on both, well under one MOA.

I wouldn't mind having several others testify to this.  I have a fear of qd's not returning to a very close zero when re-attached.  I would go for it if I knew they can and will.  I just don't dig the setup of mounting irons at 45 degrees.  Reason I ask is I actually love using iron sights and I'm sure you all do as well.  It is a very important practice and it's a kick in the ass, too.
And thanks for taking the time to post back and the info.

Top quality QD mounts from the "big 3" Larue, ADM, and Bobro, can do it.  You must return each optic to the same rail slot each time, and push the optic forward against the slot front edge each  time before locking the levers.  This eliminates rail slot variations and puts your mount's cross pin hard against the rail in the direction of recoil movement.  Do this each time with any of those three mounts and you are golden.
