US Palm and Tango Down debuted two new 7.62x39 quad stack magazines at SHOT. If you kept the existing wall thickness of a polymer mag and then opened up the stack outside the magwell to accommodate the Grendel case, you could have a nice 30rd or even 45rd mag that is as tall as a 30rd 5.56 mag.

Things are getting interesting. Unfortunatley, Surefire 60rd 5.56 mags have proven to be unreliable as I suspected they would be. Tango Down and US Palm claim that these are actually reliable, but we'll see as we go forward.
They also had a quick barrel change AK with an interrupted thread system and a detent.
