So, the M5 Oberndorf bottom metal, that JCM linked above, specifically says it “is designed for Wyatt extended length box magazines.” The standard Oberndorf bottom metal doesn’t say that. In the video below from Wyatt himself addressing potential feeding issues as solutions, he notes the potential to have machine the bottom metal.

I’m wondering if ordering the M5 version might eliminate one potential cause of feeding issues?

Don't speculate when you don't know, and don't second guess when you do.
