How could or should the 6.5 mm Grendel be improved?

Was this the one which involved testing the MP7 and P90? This is somewhat OT, but I never did hear the outcome of that - can the conclusions be revealed?

Tony - yes it was. I don't really remember the outcome - went back to Iraq when the final decision was made, but I think it boiled down to ammo availability/NATO standard. We went with issuing more M4s across the board.

My opinion, from the testing, was the P90 was a better PDW IAW the parameters we were given. Only problem I had with the P90 was I didn’t think it would be received well by the corporation due to its unconventional design.
