It appears you may be asking what is the round called fired from an assault rifle. It is a round. some are 5.56mm, some are 7.62mm. some are 8mm, some are 6.2mm (New Chinese round). Most are referred to by their chamber size.
Rounds are comprised to two components, the ball or bullet, and the cartridge or brass. As a whole, rounds are often referred to as cartridges as well.
There is no one answer- it depends on the rifle. They are generally less powerful than a full size battle rifle cartridge. The M16 rifle uses a 5.56mm bullet, the AK47 a 7.62mm bullet, etc.
If you mean the jacket, it all depends on the caliber and maker.
The M16 assault rifle is chambered for the 5.56x45mm NATOintermediate rifle cartridge. It can also accept .223 Remington rounds.
There are several different assault rifles - both by the true definition of an assault rifle and by the political motivated BATFE definition of a so-called "civilian assault rifle", manufactured by several different outfits. Which assault rifle did you have in mind, specifically?
Yes, when a bullet is fired from a rifle, the bullet typically has greater momentum and kinetic energy compared to the rifle. This is due to the bullet's higher velocity and lower mass compared to the rifle.
The force of the rifle on the bullet and the force of the bullet on the rifle are equal in magnitude but opposite in direction, according to Newton's third law of motion. However, the mass of the rifle is much larger than the mass of the bullet, so the acceleration of the rifle is much smaller compared to the acceleration of the bullet.

Rifle and bullet (The bullet is dependent on the rifle to accomplish its purpose)
Any rifle that the firing pin strikes the bullet casing right in the center of the casing, causing it to discharge is called a "Center Fire Rifle." In contrast a "Rim Fire Rifle" the firing pin strikes the edge or rim of the bullet casing causing it to discharge.
The SOAR (Special Operations Assault Rifle).
Grooves in the barrel. That is called rifling.
The first true assault rifle debuted in 1942.
