Would it be feasible to re-bore the M4 and M16 to use 7.62mm?

If not, just give our guys more .50cal sniper rifles, just with shorter range scopes.

That would be no - the problem is the lower receiver on the AR-15 series rifles. The mag well won't take 7.62x51 rounds, so you have to get a new weapon (the AR-10T) if you want the Armalite in 7.62 NATO.

That's called the AR-10.

No, because the overall length of the cartridge is too long to fit in the magwell, and the bolt doesn't go back far enough to allow them to feed.

But there are cartridges that have larger bullets and case diameters than the 5.56 with the same overall length, which will work just fine (subject to lots of tweaking and R&D, which is where good gunmakers earn their stripes.)
