OK GG&G told me that it is not meant to work in conjunction with the factory collapsible stock. They said that some customers have had luck with it fitting because the new design is thinner than previous. I am assuming that has something to do with how the threads are placed in the pistol grip. Mine how ever does not fully collapse and therefore is not 100% will be sending both pieces back.
It does however look like it would collapse fully if i were to remove some material from the grip, making the notch a bit larger, giving it the extra room that was taken away by the approx 2.5mm thick sling loop. I refuse to modify my my $2000 gun to make a $35 piece work. I guess I will be looking into the Mesa Tactical mount, which I originally did not want to to its proximity to my firing grip.
Hope this helps everyone.
