"...just buy both..." Having weapons chambered in multiple cartridges creates a logistics nightmare.
"...need Military Approval..." Government approval. The military says what they want, then the politicians tell them what they going to get. The M14 was adopted back in the mid 50's due to a political decision. The FAL beat it in every test the U.S. military did, except accuracy. The M14 was adopted because it was invented in the U.S. It then went on to have the shortest general service life of any U.S. military firearm. The M16 was also adopted due to a political decision. After both were adopted, the cartridge each rifle uses was jammed down NATO's throat by the U.S.
The original AR10 didn't perform well in any tests. Mind you, it was select fire and very light.
