I love my MIADs (and they clever storage cores) but would like them to have a slightly more vertical angle to accommodate a more squared up stance / collapsed stock (some other manufacturers have already started doing this).
Could you make new front/rear MIAD inserts that change the grip angle while keeping the same dimensions? Essentially the inserts would be more triangular - removing some material from the lower end of the rear insert, and adding some material the lower front insert. No changes would be needed to the main pistol grip component.
I think this would set your MIAD grip line apart as you can customize the insert sizes AND the angle - which no one else can offer.
