Got out to the range today to confirm my 100m zero with the Magpul MBUS Pro's. I was please with the accuracy I was able to squeeze out. From my googling I had read that I should expect 7-12moa with AR style irons.
That's quite the nonsense.
Here is today's target shot with an AR 10 at 100m , using my ultra cheap reloads:

my AR 15 shoots the same.
