Sorry- there IS no ONE "best". Ruger, Browning, Winchester, Savage, Remington ALL make very good rifles- but there are also European makers that have great rifles.
The best you can afford.
The .308 was too powerful for an assult rifle, but the US Army gave it their best try in the 1960's, equipping the M14 rifle with numerous modifications to make it into an assault rifle. As a squad auto weapon it was probably quite adequate, but the .308 was just too powerful a round for use in weapons defined as assault rifles. If other armies tried to develop an assult rifle using the .308 cartridge, nothing ever came of it to the best knowledge of this contributor.
