MagPod is currently working on their PMAG GEN M3 baseplate. They are testing two different prototypes (shown in the image below) centered around their retaining clip design that will allow them to keep their front biased design.
MagPod stated the following regarding the upcoming baseplate:
Even though the M3 PMAG baseplate slides on from the rear, we decided to make our version slide in from the FRONT, which allows us to keep the patented “forward biased” foot that MagPod is known for.
No firm release date yet – we are still evaluating the retaining clip options to see which holds up better to drop testing.
