'Best' is a very subjective term. The newest models haven't had a chance to prove themselves, so it's hard to fairly compare them.
Have never heard of an underwater assault rifle. In the US, you must be 18 to buy a rifle, and 21 to buy a fully automatic rifle.
Yes
You will need to define assault rifle, and where you live. A TRUE assault rifle is a machine gun, and transfers of them are tightly regulated by the Federal government. What most people CALL an assault rifle is nothing but a semi-automatic rifle, and in most of the US, does not require a license to possess.
The M16 is the US Army's choice of assault rifle since 1964, however, as early as 1960 its prototype, the XM16E1, was seen on the frontlines.
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.
Very basic difference is that an assault rifle is capable of both semi-automatic and full automatic fire with pull of the trigger. A rifle only fires once each time the trigger is pulled.The ammunition is important too. Assault rifles use a less-powerful ammo than rifles, but with less range. The result is that more ammo can be carried because of the reduced weight. For sniping at long ranges, the rifle is but the assault rifle has replaced it for short and intermediate ranges. In reality, assault rifle is a misnomer as it connects an action with a weapon. Any assault involving a rifle by definition means one is using an assault rifle. The M-1 Garrand rifle was a semi-automatic rifle used by American infantry throuought World War II for example. They certainly made assaults with this rifle. The same is true for the British Lee-Enfield 303 and Mauser bolt action rifles of the Commonwealth and German armies, respectively.One needs to understand that the term assault rifle has different meanings depending on the context, particularly in the US. The term "assault rifle" likely originated with the German Army which fielded a fully automatic rifle in World War II named the Sturmgewehr. Translated, this means literally "storm gun" or "storm rifle"; storm here being used as in storming the enemy. However, no other army has ever used the term "assault rifle" to describe weapons used by soldiers. The US Army and Marine Corps for example have always referred to rifles, including the fully-automatic M-16 and M4, as simply "rifles" or "weapons".Size of bullet doesn't define "assault rifle" either. The M-16 and M4 indeed fire a relatively small bullet, the 5.56 mmX45mm NATO round which weighs just 62 grains, although the cartridge is fairly large. On the other hand, the most widely produced fully automatic rifle in the world, the Kalashnikov AK-47, fires a bullet weighing 123 grains.Really, "assault rifle" is a term used principally in the US and outside the military to define just about any type of rifle that is semi- or fully-automatic. Those new to the US should understand that the term is generally used by the media and anti-gun advocates. And, again, beyond this there is no weapon or ballistically defined "assault rifle."Short Answer: a rifle fires a full-length long-range cartridge as a single shot or semiautomatic weapon. An assault rifle fires a less powerful close-range cartridge, and has full-automatic capability.
