Not really related but Spartan referring to it as a DI gun made me wonder, does anyone know what the technical name for the gas system in an AR-10/15 is? It isn't a DI as most people call it, that is where the gas just blows on the bolt carrier to push it back, whereas the Stoner system routes the gas tube into the bolt carrier which effectively becomes a piston pushing the bolt carrier backwards until the bolt unlocks and cycles the action.
Anyway, whatever the system is actually called, I agree that there is nothing wrong with picking that as a design. It has disadvantages, but it also has advantages. In my opinion it is much more likely that the US will carry on with the M4 PIP program than going for a totally new carbine.
