No, to the best of my knowledge, it doesn't exist -- which is more or less my point. Is anyone aware of discussion (formal or otherwise) along these lines in view of the recent E/PMAG product line expansion?

I realize Magpul is extremely reluctant to release information on products in development, but this would seem to be a no-brainer, provided the development costs could be kept to a minimum. With more and more shooters considering the addition of at least one 6.8mm-based platform to their arsenal, wouldn't a SHOT 2010 debut make a certain amount of sense?
