+burger1690 Cause the mistake was not in the rifle, but in the cartridge. It was clear from the start (and I mean the start, from the Federov Avtomat, if not from the Cei Rigotti) that "select fire", in a weapon with the weight of a rifle, required an intermediate round to make the burst controllable. For that reason the British, after the war, proposed the 7mm British as the universal NATO cartridge. But the US Army didn't accept a round less powerful then the 30-06, so the 7.62X51 was adopted instead. The British, discouraged, adopted the FAL in semiauto only, cause, with the 7.62X51, the possibility to control the burst was only theoretical. The Italians made the BM59, with a complex muzzle brake and an integral bipod, to make it's burst at least a bit controllable, and the US replaced the M14 as soon as they realized that the guy with the M14 was outgunned by the guy with the AK-47.

Bring me Peter pan "m14s were full auto?"
Yes and no. They could have, or not, the selector installed. Originally the M14 was intended to replace the M1 and the BAR with a single design, but the conception was still that of the riflemen squad, with the M14 in semiauto only, supported by LMGs, that were M14 with the selector and the bipod.
But, when the soldiers begun to fight enemies armed with assault rifles, many formations switched all their M14 to full auto. At least to have a higher volume of fire.
To hit what you was aiming at, was another story.
The problem in using a full power cartridge like the 7.62 NATO in full auto is triple. There is the recoil, there is the muzzle flip, and there is the spin that the bullets give to the rifle (the reaction to the bullets being put in rotation by the rifling). The shooter, instinctively, tend to compensate the muzzle flip, so the burst tend to widen in a spiraliform pattern.

To make it shoot from a mag and be select fire, but none of the thecnical solutions had been reused.
The MB59 actually "made it right". It uses a proprietary mag that feed reliably. A straight op rod, more apt to full auto fire than the original bent one. The selector is completely different, it links the op rod with the sear, so that, only when the action is in full battery, it releases the hammer. That way the action is safer and more reliable, and the ROF is reduced to 750 RPM. It has a muzzle brake that compensates the recoil, the muzzle flip and the spin that the bullets engaging in the rifling give to the rifle (the last seems a minor issue, but it's actually what makes the bursts in 7.62 battle rifles uncontrollable, since the shooter instinctively tends to compensate the muzzle flip, but can't compensate the spin, so the burst widens in a spiraliform pattern). Every rifle was provided with a bipod, to function as a squad LMG when needed.
