The Sig Fury will never fly. A loaded XM7 or whatever it is weighs 12 lbs loaded. It will be tested, evaluated and then it will be destined for Speacial Ops for specific requirements. The fastest way to get performance is to use either 6.8 SPC or 6.5 Grendel.
I prefer Grendel for the reach out it can give you. The SPC dose not require a bolt change, the Grendel Does. But the Army has also adopted the 6mm ARC ( little brother of the 6.5 Grendel) for specific applications. So my guess is either 6 ARC or 6.5 Grendel for infantry , light weight, low recoil. Familiarity with operating as identical to M4.
Of course this would be the most economical and feasible way to go with transference of parts from the M4. But that makes sense. Not sure that the upper level brass in DC are capable of that.
