Even though I do not own an AK, I agree with you. The AK is probably one of the most reliable (if not THE most reliable) rifle of military usefulness currently available – though in fairness, I have not seen anyone do destruction testing on all modern rifles and then compare the results. That kind of thing gets expensive.
However, a question- given that the 7.62×39 is a basically a ballistic match for the American .30-30, why didn’t you obtain an AK platform rifle, but chambered in an American caliber? That way, you’d have the reliability you want, plus the advantage of a common caliber…
A Saiga in .308… I think you can retrofit this with regular AK furniture..
