update on MIAD and wedge: so, it turns out that the wedge is not an easy fit for the MIAD plus the lower receiver size on these rifles. I had to do some cutting out/remodeling to get it to fit. The space between the beavertail and the receiver is much thinner than the wedge was made for, in addition to the metal rib that the grip is screwed into is longer at its base and you have to cut out that section of the wedge so it will fit on easily.
