Manufacture venders have been using the M-16/M-4 frame for years as a selling feature. All soldiers would have instant muscle memory familiarity. The commanders would have the option to tailor his firepower for the combat environment without having to acquire and train to a new weapons system.
Just curious.

Way to dig this thread up from the dead.
The military can't just supply itself with a new cartridge overnight. Since a 7.62x51 NATO obviously won't work on a M4 lower you would need something similar in length to the 5.56x45 like a .300 Blackout. The problem is, I don't think it is going to solve the range problem since that bigger round (the blackout, or similar .308 variant) would likely lose effective range.
The answer could probably be found somewhere between better marksmanship training/more range time and getting more M14s/AR-10/SR-25s and M110s on the battlefield.
