M16 Assault Rifle

The M16A3 assault rifle is a Tier 2 replacement for the submachine gun with higher damage and better accuracy. It holds 50 rounds with a 360 round reserve, having less total ammo then the uzi, but being a better overall weapon. The M16 is the best choice as a general use firearm, as it is adaptable to most situations.

Tactics
Assault rifle ammo is easy to waste. The weapon trades ammo capacity for accuracy and damage, and this must be used to full advantage to be effective. The assault rifle generally needs only two or three shots to do its job, and any more hampers its accuracy at mid to long range. Thus, burst firing is highly recommended at medium to long ranges as this not only helps improve accuracy, but this also has the benefit of conserving precious ammo.

This weapon is extremely useful when playing on higher difficulties because friendly fire can cause just as much if not more damage than infected and the assault rifle does not have a cone of fire such as a shotgun, meaning that it is easier to avoid hitting teammates inadvertently. So while you do chew through ammo very fast, it has good damage, accuracy, and reload speed, making it highly useful and a good pick for those seeking an all-around, all-range weapon.

In a group of 4 on Finale's Its a good idea to have 2 people with Pump/Auto Shotgun and 2 People with Assult Rifle, Get in a closet, The two people with the shotguns crouch and shoot/melee, while the two people with the assault rifle stand and fire rounds into the infectes trying to get through the door
