How much does your zero shift when changing out barrels?  Just curious, as I only have one (for now).

Each rifle is a little different...I average about 1-2 MOA variation with my MSAR (which is not a STEYR).

Im usually within an inch or 2 when pulling my barrel and putting it back, but if I take it apart to clean it gets retired from duty until a re zero happens

I've never rezero'd my iron sights on my A3 (troy micro's) when switching between 16" or 24" 5.56 and 16" 9mm.  I just know my point of impact shifts up and down a bit between calibers and barrel lengths, as one would expect.  I only recently decided to mount an optic though, and I've not zeroed and tested with it yet.

My rifle maintains its zero, Iíve taken it off and on dozens of times without re-zero. I have not tried it with multiple barrels, but the AUG should not need rezero after taking the barrel off and on

Same here, neither of my AUGís showed discernible poi shifts after multiple removal and return of the barrels. I zero at 200 as well. I typically see a bigger poi shift with ammo types and brands.

This.  AUG's return to zero well within the accuracy of the rifle, so long as it's the same barrel going on and off.  If not, something is wrong.

This has been my experience also...no discernable change in POI.  I never knew this was "a thing" on an AUG and hadn't seen it mentioned before.  I pull my barrel when I clean it.  Never have seen a change in accuracy.  I use a 1-4 scope with a red dot in the reticle, so it provides very decent target acquisition at 100 yards.  Nothing changes unless I use very different ammo.
