Light Primer Strikes on MP5

Surprised there weren't more posts about this. Found one from 5 years ago with no responses. Hopefully this one will get some more traction.

I recently started getting light primer strikes on an AP5 with only about 750 rounds on it. Has anyone else experienced this or anyone knowledgeable on the platform know what a likely culprit could be or what parts I could swap to possibly chase it down?
