Very interesting!!! There is a very good article on this on www.tacticalshooter.com , october issue. Two comments: they could easily use a heavier barrel to solve the "thin chamber requires a proprietary steel alloy" problem, and, if bolt shear strengh is a problem why not use the much stronger AR10 or Stoner 308 rifle as a base? (just like the AR15 receiver is used for 40, 9mm and 357sig conversion). This would also provide thicker mags for better staggering of the rounds.
