From the article: "The larger 7.62 rounds employed in AK-47s come with far more recoil than you’ll find with a 5.56, making it tougher to land a second and third shot with as much accuracy, depending on your platform."

The AK-47 employs a piston whereas the AR is normally Direct Impingement. The movement of the piston and ensuing effect on the firearm affects follow-up shots.

[Alas Babylon!]

Not all rifles that fire the 7.62X39 are AK or AK variants.

I love my Ruger Mini 30.

That calls for Plan B. Spray and pray.
