Ok folks, as a matter of fact I'm also working on some weapons, and in particular in accurate depictions of the AKs, including the newer AK-74, AKSU-74 etc.
Here is the screenshot of my nearly finished AKS-74 model, yet to be UV Mapped & animated.
What I've noticed is that in the model pack 5 although all other weapons are very nicely modeled, I have the impression that the AKM has a serious flaw since the cocking bolt (& shell ejection) are positioned on the left hand-side instead of the right one, so I was going to correct that
Cheers,
Caleb
