M16 Assault Rifle

The M16A3 assault rifle is effectively an upgraded submachine gun with higher damage and better accuracy. It holds 50 rounds with a 360 round reserve. Damage output and accuracy effectively compensates for a lower ammo reserve. This is a very useful weapon. It's great for taking out a horde at long range or even do serious damage to a Tank or Witch at medium range. If you find yourself surrounded, the gun can take out a large chunk of the horde, but it wont "feel" solid. shoving enemies away before taking them out is usually better than spray and pray in that situation.

The skin in game reveals this particular M16 to be manufactured by a fictional company called American Armory. It is incorrectly labeled as an M16A2 on the side (the M16A2 is the same as the M16A3 except that the A2 cannot fire in full auto).

Tactics and the Assault Rifle
Much like the submachine gun, ammo expenditure is a big problem with this gun. Random firing in any direction will take its toll as ammo reserves dwindle. Due to the fact that the reserve on this gun is lower than that of the submachine gun, careful shooting must be taken into account when using this weapon. In most cases, burst firing by firing two or three rounds at a time not only conserves ammo, but improves the accuracy of the assault rifle at longer ranges.
