Same here - My SLG-21 Saiga performs similarly in the 2-2.5 MOA neighborhood.
I actually prefer the AK sights over the AR (though I'm using EOtech and Aimpoints on my ARs now, but still iron sights on my AKs).
I won't go that far. I find the AR aperture sights to be vastly better than AK sights in just about every respect.
But it's as Taliv said - it's all about managing expectations.
