They specifically tuned the M14 in the cold chamber used for the trials.
FN tuned the FAL somewhere else. It was an unfair home field advantage and the US should have sucked it up and adopted the FAL to have some NATO compatible supply chain and if the US was really smart they would have accepted the 7mm optimum chambering to get the US in to an intermediate cartridge that's lots better than 7.62x39 back in the 50's.
Our military has wanted a cartridge with better terminal ballistics than 5.56 for decades. We have never got it because it's hard to improve and stay within the limits of the M4 envelope.
We could have been way ahead of where we are now back in the 50's.
