Also, the reduction in rear trunion rivets on the newer models can't be helpful to the situation either.

Seems to me the structural integrity of the receiver would be compromised in this area of the NPAP more so than with the Saiga conversion holes because of proximity to the heavy BCG reciprocating mass during live fire on the NPAP.
For the holes to not have been stressed, the innards would have to've been tight enough not to be functional, so "yep, cracks away!"

As I mentioned earlier, with this design choice, stress cracks are gonna show up early ( compared to standard AKM receivers )
