I've got a MAK-90 in 223/5.56 with a MOJO peep sight on it, it's the most accurate AK I've fired...I feel pretty good if it holds 3 moa with "selected loads" and a touch of luck. It's rather instructive using a RCBS precision mic when sizing brass for these finely constructed rifles.
I'll agree that the SKS is a far superior rifle, as far as accuracy, when compared to the AK or Mini-14.
