I currently have several different optics that I would like to be able to exchange on one AR.  One is a Super Sniper scope on an Armalite one piece base.  The other is a Trijicon ACOG.  Right now the Trijicon just has the standard flat top adapter with the two thumb screws, but I want to get a Larue or A.R.M.S. mount with throw levers so that it is easier to get on and off.  

I believe that one of the big benefits of the throw lever mounts is that it allows you to take the optic on and off and be able to repeat the zero as long as you mount it on the same spot on the flattop.  Is this indeed true?  If not, how big of a difference is there in the zero?

Is there this sort of repeatability in the Armatlite mount or does the presence of the thumb screws make it too difficult to make sure that there is the same amount of force each time you put the mount back on?  

Thanks.

with a good throw lever mount it has it would offer repeatable zero and i have never had a problem with zero when removing my optics since i do that each time i clean them. all of my optics are mounted in larue tatical mounts.
